I've been off-line for a few days while I upgraded my PC (a long slow process of reinstalling things).
The image above was done in Paint Shop Pro X using my graphics tablet, in about 2-3 minutes. It works! And the Photoshop file I had for my honours project (20 MB, multiple layers) loaded into Photoshop CS 2 in only one second! Looks like I'll be ready for uni next year.
