How to handle pop-up window using Selenium? ("driver.switchTo().window(winHandle);" not working consistently)

Question

We are facing some issue in switching to new window after clicking on the link/button

I was using the below code for switching to new window.

elem.click();
for (String winHandle : driver.getWindowHandles()) {
driver.switchTo().window(winHandle); }

Observed that scripts runs inconsistently, It will be great if i get some consistent code for switching to new window. I feel there is a synchronization issue while switching to new window.

If @HelpingHands suggestion will not work the problem may lies in the several handlers exist simultaneously The following code may help: When you create the driver please save the appropriated handler

driver = new FirefoxDriver(profile);
driver.get(uri);
MainWinHandler = driver.getWindowHandle();

Then in order to switch

for(String winHandle : driver.getWindowHandles()){
    if(!winHandle.equals(MainWinHandler))
        driver.switchTo().window(winHandle);
}
