Of course.  But this need to make sure the window which has input
focus is the one you think it is, is something routine in a windowed
environment, IME.

Happens to me all the time, and at least sometimes for good reasons:
for example, if a program pops up an abort dialog, it is completely
reasonable for it to steal focus.  Similarly any other event that
requires an immediate attention from the user.

Once again, you assume that nothing happened except switching
desktops, but that assumption doesn't have a very solid basis.

But I guess we will need to agree to disagree here.
