>This is not a joke but one .aspx page which was opened in one project suddently jumped into another project. Basically, that .aspx doesn't even appear in that project list of components and it appeared just like that as an opened file in the IDE. I never saw anything like that. Is this a joke someone did in the interface?

May be some strange combination of keyboard keys caused that?

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.

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.

And, the most annoying problem, that when I type something, sometimes the cursor will jump to a different place. This problem I noticed on many laptops I used.
