I have a really old version of Photoshop which I purchased many years ago on Student Licence. I also have PSP Anniversary edition which my brother bought for me as a birthday pressie many moons ago. I love PSP - before Corel got their mitts on it, it's lightweight and very fast. It also has one of the best screen cap functions Ive ever seen.
Windows 10 doesnt seem to like either program, although after much tweaking and many re-installs this morning I have got some functionally back. For eg PSP kept crashing and Ive been able to overcome that by manually setting paths and running in XP compatibility. I cant yet get it to open any .psds that I created with it :/ I've been searching on the net re Photoshop, and its a common problem. Of course Adobe dont care because its a very out of date version. I ran into a similar problem with Dreamweaver, the whole site runs on a dreamweaver template I created, but luckily that seems to work ok in compatibility mode although I haven't yet had chance to work on any files in it. Most of the problems seem to be with graphics progs on windows 10.
My PSP licence and Jasc membership still allows me a discount for Corel purchase which is why Im currently testing the trial version, but I'm not sure if I like it.
The issue that I have is that I have a LOT of .psd files. Most of the site images are stored as .psds which now concerns me because there is no way I can afford Photoshop CC - its silly money. PSP allowed me to open, edit and store .psds quite happily.
However look at a screen cap below of the site logo. Despite Corel supposedly supporting PSD's its obviously not handling grouped layers.
Ive just noticed that GIMP maintains .psd support so I will definitely give it a go and see if it fairs any better
