Debug won't sork after SP2

OK, I did it. I installed SP2 on my XP Pro system and now
when I press F5 in VS, the apps window doesn't appear. I
can "Build" the solution and run the "exe" separtately
but not thru the debugger. I have try doing what is
suggested in MS KBs 875357, 833977 and 842242. Nothing
has helped. Where do I go from here? Thank you in advance
for your reply.
