Just Upgraded to 10.5.4 from 10.4.on a G5 Dual 2.5 GHz w/3.5 gig ram (at this point can't go higher because of other apps Problems) When I open a Photoshop file that is missing fonts, I tell it ok, but then I get message - Could not complete your request because of a program error. On other machines it works and others it does not. I can open in CS2. Any suggestions?
