I have Firefox 7.0.1 loaded on a Windows XP Pro machine with multiple Windows user accounts on it. Firefox always crashes on startup under one of the user accounts, but works fine under all others. I have attempted to delete the Firefox profile(s) under this user account, uninstall Firefox completely, delete the program directory, and even cleared out all temp files from my PC. I even went so far as removing any references to "Mozilla" or "Firefox" from the windows registry. But it still does the same thing after reinstalling and starting the program back up under the one user account. The crash id that is generated is listed below. Thank you for any help you can provide. Note: Reinstalling the OS is not an option.

Crash ID: bp-5a5be570-db63-4304-847f-6b1d02111011
