>May be some strange combination of keyboard keys caused that?

Probably but this reaction is totally out of proportion.

>BTW, remember you mentioned some problems with some strange hitting of the keys? I notice quite often when I have SSMS opened, all of the sudden a new query window would open when I'm writing code in another window.

Mine was related to the F1 which was trying to launch some kind of online help. When I disabled that, I didn't get any other problem after.

>Or, when I'm working in VFP, say, and have multiple VFPs session opened, suddenly some other window will open when I was not trying to open it.

The only other issue I have with the key is the ESC key which is disabled when Photoshop is loaded, such as reported by Tracy. Probably when I will upgrade to the newer version, this would be fixed.
