I am seeing a similar problem. X1 has suddenly decided to keep popping up, especially if I browse to another folder in Windows Explorer. It has become a major nuisance only since last week; for me it seems to be unrelated to Outlook - could it be related to Windows Updates?
I have also noticed that sometimes it is quite hard to get X1 to stay closed; sometimes it pops open again immediately when it is closed, and I need to re-close it several times before it will stay closed. Again, this appears to be related to use of Windows Explorer.
