The one that hurt me going to Win7 was Photoshop Elements. I've been using ver 2 for about 5 years, and it works great; but Win7 says it doesn't have a valid certificate and demands an Administrator password every time I open it.

I bought PSE 7 when Vista said something similar, but it was so crapped up that I ignored the warnings and put PSE 2 back on. Vista ran ver 2 okay, and gave me lots of "warnings," but didn't keep asking for Administrator. I bought PSE 10 for Win 7 in the vain hope it might be better, but it was even worse, with illegible (nearly invisible) and unintelligible icons all over the place (they show as indistinguishable blobs), many useful functions removed and others hidden so deep it takes 12 clicks to do what 2 would do in the old one. There are lots of useful things I can't find a way to do, and the "work space" is so cramped you can't enlarge anything enough for detail work. (The invisible icons take up the whole screen.)

I have both ver 2 and ver 10 on the machine, but I use #2 for almost everything. F**k 'em if they can't take a joke. I've found a few things I have to "do backward" but I'm getting them done.
