on AMD dual processor. Please help,thx. This is running well, except for the three or four times a day that it "locks up". I get the error message that says" Photoshop has encountered an error and needs to close now........." The worst part is that the work that has been done but has not been saved is just gone. I am frustrated, since almost all lock up issues o the forums seem to be about installation problems, I have had not one installation problem. Please help. Thank you.
