I use Jasc PSP 9. When I try to crop a picture that is large (above 500 pixels), PSP freezes. I try to exit the picture, but a box shows up that says "An image processing function is currently in progress on this document. The document will close when the processing has completed." Of course PSP just sits there and doesn't close. Also, Ican't edit any other documents that are open during this "process". Everytime, I end up hitting alt+ctrl+delete. Is there any way to fix this? It's bugging me.

(This is especially problematic when I'm icon-ing screen caps.)
