I continued using Paintshop Pro on an old XP computer, long after its sell by date. One of the few reasons I'd boot that old computer instead of using Gimp on Linux Mint. I'm gradually getting into Gimp now but the learning curve is so steep I need grappling hooks. I still struggle to do basic things I did with ease in Paintshop Pro like draw a straight line of a certain thickness and colour - it tends to just stick in a line of its own choice of colour or thickness and won't let me undo it if it turns out wrong. Granted Gimp seems to have a zillion features (that I never use), but I just find it slow and irritating to use. I also find it pedantic that you can't save to JPG / PNG and have to export to it. I know they are lossy, but that is often the format I need to save to for subsequent applications to use.
