Recently, we had to reinstall the operating system (Don't ask! lol), and now IE seems to just drop to the desktop on a whim. I have tried to see if a pattern would emerge, but none so far have come up. No one site, and no one situation seems to be the culprit, so the next step appears to be uninstalling, and reinstalling IE.
We are using WinXP.
If you have any suggestions, they are most welcome.
