I am running Windows 7, Outlook 2007, and 5.1 with the TWC version. Outlook crashes at least twice a day with a message that the ClearContext add-in is the problem. I can disable it, but that is not a long-term solution. If I don't disable it, I eventually get a message to run scanpst.exe and I do, which takes forever but resolves the problem until the next day when it crashes again. Is there a conflict between TWC and 5.1?
