I agree there's some indication somewhere that there is a window / dialog
waiting for input, but, the OP has a valid point. These dialog boxes should
take focus and be placed on top of any open windows. It's how XP worked, 2K
worked, AFAICR, 9x worked NT worked, and 3 worked. It is not unreasonable
for the OP to assume 7 should work that way as well.
Actually on occasion, any and ALL of them could and would end up with
the dialog asking for user confirmation behind the main window of a
program. The MOST frequent offender was Adobe Reader.
