I was just wondering if you were sharing my problem.. It's because when I change the name or any text for a unit it takes long time... more than 10 secs.. it's not because my computer is slow... My cousin is also having that problem and he has a monster-computer... Before i reinstalled windows, it was very fast at changing units name.....
I have the same problem, but I believe, it's just from having alot of stuff downloaded on the computer. I have a good computer too, but since I've been downloading things from this site, it's been slowing down some.
it might be a lot of things.. first you could set off your brush list (Window-->Brush List) make sure you dont have spywares or too much opened programs, they both have the potential to use a bit / most of your memory
Another trick to save at least some memory, and speed up the progress, is to go to file-> Preferences, and set the undo limit to something lower... like, 30 or something.
Sorry to bump, but go into windows, and TURN OFF THE BRUSH LIST! I didn't mean that as an insult, but that is the most common cause of unit creation lag...
