I tried a search for this problem in Google just in case it was common, and it seems to be a long standing problem that people have had with IE. The problem is that there was no single solution. People mentioned everything from cookie settings to anti-virus software to clearing the cache. So I'm going to make the radical suggestion that you try a different browser, such as Firefox or Chrome. If you don't have a preference between the two, then I'd make a case for using Chrome because of the Wikitree-X tool that lets you easily add information to profiles and create new profiles. But if you prefer Firefox, go for it. If the problem persists in your new browser, then we can say, well, it's not the browser--maybe it is your computer antivirus settings. If the problem goes away, then I'd chalk it up to an IE quirk. Also, although I've done lots of troubleshooting over the years and managed multiple computer labs, there's bound to be someone who knows more than I do who will most likely log in and see this question and know the perfect solution. But for now, I would start with a different browser. Let us know how it goes.
