IE crash problems when using TestComplete

So, it crashes on launch?  Is that what you're saying?  If that's the case, then no, I'm not experiencing that problem.

Something you need to make sure of... IE sometimes tends to hang around in process memory after it has been closed.  When you close a browser instance, you should make sure all copies of the process have been closed as well.  I've experienced situations where, if I didn't do this, a number of strange problems would happen.  

The following code is what I use to ensure this

function closeIEInstance() {
    var counter = 0;
    var browser;
    browser = Sys.WaitBrowser('iexplore', 1000);
    while((browser.Exists) && (counter < 60)){
        counter++;
        browser.Terminate();
        browser = Sys.WaitBrowser('iexplore', 1000);
    }  
}
