I have a customer who has both IE8 and FireFox on her Windows XP SP3 system. She uses FireFox for pretty much everything. However, she has a shipping program that seems to rely on IE8. I thought AVG was the problem, but she has done some playing around and found something interesting. If FireFox is OPEN, IE8 will hang loading a page, hence her software will not work. If she closes FF, then IE8 opens and her software(Dazzle) works just fine. Now, I have done the "reset" of IE8, cleared everything, tried running as "no add-ins", etc. Are there any known conflicts like this between IE8 and FF being on the same system? If there are, are there any work arounds?
