Last weekend I installed CS4 the latest verson and wasted an entire afternoon cursing. Would not install until I upgraded Windows so I did that. Twenty minutes to download the patches then a hour as the blasted computer installed them. Now with Adobe I have no idea if all the crap they send (only realy wanted Photoshop, Dreamweaver, Flash) I actually need but dropped most into the machine so that took another chunk of time. This doesn't include the house cleaning done on the hardrive. Blasted thing runs like a bloated pig now.
Photoshop there doen't seem that much of a difference between 2 & 4. Slightly different organization, haven't done much experimenting yet but I'll work in it. Annoyances: I can't seem to find a clear button to make cleaning an area easier. The other aggrivation the fact that while painting it didn't seem to be doing anything when I was trying to put some highlights in. Then looking back in a lower magnification I realized that what I had just painted was somewhere else on the body.
I'll figure out something at some point.
