Terminatrix,
am i correct in assuming you are in the GIMP Dev Team? If so may I suggest (if this is written in C++) when you recieve your WM_CLOSE message add this little tidbbit of code:
Where hwnd is your window handle. You can change the icons, and button ect. but pop up a message on close, so people know the program is exiting and their computer didnt freeze, because The GIMP seems to do some pretty CPU intensive processing on WM_CLOSE.

Pros: dude spider man is kewl, but green lantern is better :D

Pros: Wow, I like the Flames.
Cons: The white bars on the side are not cool.
Improvements: whats with the white haze on top half?
Notes: very nice over all!

Pros: Lovely radar :D
