winword.exe apparently uses a while (PeekMessage()) loop.

This adds a timeout of 10 milliseconds so we are still interactive, but do not take up as much CPU. (We basically wait 1 timeslice if 100HZ scheduling).
I question this... an app could be doing something important in such a loop, i.e. while (!PeekMessage()) do_a_piece_of_important_stuff(), and this would severely slow down things like that. In particular, I expect a lot of games to use such loops. If you need CPU time reduction, at least make it configurable.
Me too. There are (badly written) applications that suffer greatly from this. Furthermore I did some tests on Win 95 and Word 97 only does that with some files, not all. Also, Word 2000 no longer behaves that badly.
Now, if it were a per application setting it could make sense.
