IE processes dont terminate

I want to have a clean up before I start to run a batch of tests. So, I used the code from the documentation to close all the browsers

<--

function Close()
{
while (Sys.WaitBrowser().Exists)
Sys.WaitBrowser().Close();

}

-->

 

I dont use IE but the code hangs on ' waiting iexplore processes to close' 

I have tried the code from TestComplete does not appear to close IE11 correct... - SmartBear Community

and before closing all browsers, close ie. 

I has the same effect, it hangs on '  waiting iexplore processes to close' 

 

Anyone?

 

Thanks!
