Myself have Adobe 6 and it seems to want to take over my computer. Maybe it might be just me.
Have also PaintNet. It is FREE and I get updates for free about every 45 days. Also it might be me, but cant get it to do all I want.
So I use MircoSoft photo editing, that also cant do all I want.
So ending up using PaintNet, and Mirocsoft hand in hand to get it done.
Gimp2, is suppose to be the cats meow, have that also, but never used it, opened it up and looked like mess, so never took the time to see what it is all about.
