Any of those help It might have something to do with your node version. I had the same problem with node v10.7.0. After an upgrade to v11.6.0 it started working again.

With these it helps Few issues: 1) You're not calling or initializing the thread correctly. 2) You need to tell your main thread to keep processing events while the other thread is running 3) Your label is hovering over the 'exit' button, and therefore you'll not be able to ever click it!
code :
import sys
import datetime
import time
from PyQt4 import QtCore, QtGui

class Main(QtGui.QMainWindow):
  def __init__(self, parent=None):
    super(Main, self).__init__(parent)       
    self.b = QtGui.QPushButton("exit", self, clicked=self.close)

  def myRun(self):
    while True:
      time.sleep(2)
      print "Print this + Show the Window???!!!"      

if __name__ == "__main__":
  app=QtGui.QApplication(sys.argv)
  myapp=Main()
  myapp.show()     

  thread = QtCore.QThread()
  thread.run = lambda myapp=myapp: myapp.myRun()
  thread.start()    

  app.connect(app, QtCore.SIGNAL("lastWindowClosed()"), app, QtCore.SLOT("quit()"))

  sys.exit(app.exec_())

  while thread.isAlive():
    #Make sure the rest of the GUI is responsive
    app.processEvents()

should help you out Currently, your code is reloading the page every time your LoadById or LoadByName functions is called, because it's doing this:
code :
var newWindow = window.open('../search/searchPage', 'mywindow', ...);
var newWindow = null;

function LoadByName(windowHeight, windowWidth) {
    if (!newWindow) {
        var centerWidth = (window.screen.width - windowWidth) / 2;
        var centerHeight = (window.screen.height - windowHeight) / 2;
        newWindow = window.open('../search/searchPage', 'mywindow',
                'resizable=0,width=' + windowWidth + ',height=' + windowHeight
                        + ',left=' + centerWidth + ',top=' + centerHeight);
        alert("Name window");
    }
    newWindow.showDiv(2);

}
function LoadById(windowHeight, windowWidth) {
    if (!newWindow) {
        var centerWidth = (window.screen.width - windowWidth) / 2;
        var centerHeight = (window.screen.height - windowHeight) / 2;
        newWindow = window.open('../search/searchPage', 'mywindow',
                'resizable=0,width=' + windowWidth + ',height=' + windowHeight;
    }

it helps some times In response to the question, the original poster might want try changing the spelling of the word below within the code posted.
code :
(defun lawlist-split-window-below (&optional size)
  "Split the selected window into two windows, one above the other.
The selected window is above.  The newly split-off window is
below, and displays the 'next-buffer'.  Return the new window.

If optional argument SIZE is omitted or nil, both windows get the
same height, or close to it.  If SIZE is positive, the upper
\(selected) window gets SIZE lines.  If SIZE is negative, the
lower (new) window gets -SIZE lines.

If the variable `split-window-keep-point' is non-nil, both
windows get the same value of point as the selected window.
Otherwise, the window starts are chosen so as to minimize the
amount of redisplay; this is convenient on slow terminals."
  (interactive "P")
  (let ((old-window (selected-window))
    (old-point (window-point))
    (size (and size (prefix-numeric-value size)))

Hiding Tkinter root window while showing modal window

Hiding Tkinter root window while showing modal window

wish of those help It seems that in your case there is no difference, modal window or not. In fact, you just need to use the wait_window() method. According the docs:
code :
from Tkinter import *

root = Tk()

def go():
   wdw = Toplevel()
   wdw.geometry('+400+400')
   e = Entry(wdw)
   e.pack()
   e.focus_set()
   #wdw.transient(root)
   #wdw.grab_set()
   root.wait_window(wdw)
   print 'done!'

Button(root, text='Go', command=go).pack()
Button(root, text='Quit', command=root.destroy).pack()

root.mainloop()
from Tkinter import *
from ttk import *

class TkGui(object):
    def __init__(self):
        self.root = root = Tk()
        self.root.withdraw()
        selector = FolderSelection(self.root, ('foo', 'bar'))
        self.root.deiconify()
        print(selector.result)

class ChildWindow(object): #Base class
    def __init__(self, parent, title):
        top = self.top = Toplevel(parent)
        self.parent = parent
        top.title(title)
        f = Frame(top)
        self.create_controls(f)
        f.pack(fill=BOTH, expand=Y)

    def create_controls(self, container):
        pass

    def make_modal(self, on_cancel):
        #self.top.transient(self.parent)
        #self.top.wait_visibility() # Python will hang here...
        #self.top.grab_set()
        self.top.focus_set()
        self.top.protocol("WM_DELETE_WINDOW", on_cancel)
        self.top.wait_window(self.top) # ...or here, if wait_visibility is removed

class FolderSelection(ChildWindow):
    def __init__(self, parent, folders):
        self.parent = parent
        self.listvar = Variable(parent)
        self.folderlist = None
        super(FolderSelection, self).__init__(parent, 'Select folder')
        self.result = ''
        self.listvar.set(folders)
        self.make_modal(self.cancel)

    def create_controls(self, container):
        f = Frame(container)
        Label(
            f, text='Please select the folder '
            'you would like to use.').grid(column=0, row=0)
        self.folderlist = Listbox(
            f, listvariable=self.listvar, activestyle='dotbox')
        self.folderlist.grid(column=0, row=1, sticky="nsew")
        Button(
            f, text='OK', command=self.ok
            ).grid(column=0, row=2, sticky="s")
        self.folderlist.bind("<Double-1>", lambda e: self.ok())
        f.pack(fill=BOTH, expand=Y)

    def ok(self):
        if len(self.folderlist.curselection()) != 0:
            self.result = self.folderlist.get(self.folderlist.curselection()[0])
            self.top.protocol('WM_DELETE_WINDOW', None)
            self.top.destroy()

    def cancel(self):

will help you I'd suggest a different method. The way that I'd recommend doing this is to create a small manager object for displaying the dialog window, through which you can pass parameters to the dialog window's view-model before it's used to create the window itself.
Create factories for your window and view-model, and use them something like this:
code :
public class DetailsWindowDisplayer : IDetailsWindowDisplayer
{
    private readonly IDetailsWindowFactory windowFactory;
    private readonly IDetailsWindowViewModelFactory viewModelFactory;

    public DetailsWindowDisplayer(
        IDetailsWindowFactory windowFactory,
        IDetailsWindowViewModelFactory viewModelFactory)
    {
        this.windowFactory = windowFactory;
        this.viewModelFactory = viewModelFactory;
    }

    public void ShowDetails(IPersonViewModel personViewModel)
    {
        var windowViewModel = this.viewModelFactory.Create(personViewModel);
        var window = this.windowFactory.Create(windowViewModel);
        window.Show();
    }
}
public interface IDialogWindow
{
    void Show();
}

public interface IDetailsWindow : IDialogWindow
{
}

public class DetailsWindow : Window, IDetailsWindow
{
    // The Show() method from IDialogWindow is automatically implemented
    // by the WPF Window class
}
