What about your VGA Cards ?!
If everything is ok in photoshop, The problem will be in the VGA/GPU Card.
Thanks, I'm not sure what that is. I googled it, and it looks like a computer part. My iMac is only 2 months old. The problem just occurred mid project today. I just added the free trial of indesign today, but photoshop was working fine for a few hours after that.
I keep getting a message about converting from 32 bit colorspace. Could it have something to do with that? Sorry I haven't used these programs in about 9 years, so I'm not so great with this stuff.
