IEdriver in Selenium [duplicate]

I am trying to navigate between windows in IE.am using IE version 11 on windows 10 (64 bit) and updated IEdriverserver (2.39) for the same. But the code gets stuck after the new tab is opened.

String mainWindow = driver.getWindowHandle();                                        
Set<String> set = driver.getWindowHandles();
System.out.println(set);
Iterator<String> itr = set.iterator();
while(itr.hasNext()) {
   String childWindow = itr.next();
   if(!mainWindow.equals(childWindow)) {
        driver.switchTo().window(childWindow);
        Thread.sleep(1000);
        driver.manage().window().maximize();     
        driver.navigate().refresh();
        System.out.println(driver.switchTo().window(childWindow).getTitle());
   }
}

The same code is working fine in the chrome. I think there is some issues with the Ie part. Can anyone please help me resolve this ?
