HELP!! I have just installed (and re-installed in case that helped - it didn't) The Adobe CS2 Professional Suite on my Dual G5 running OSX 10.4.1 and Photoshop keeps locking up completely - the only way to get out of it is to do a forced quit from the Finder. Anyone got any ideas? This is really serious as this is my livelihood here and I have a book to finish ASAP. I have been running 2 gig ( 4 x 512s since I got the machine) of ram and have just installed a 3rd gig (2 more 512s) from a reputable supplier which according to system profiler is the same specs as my other ram. Could this be the problem? No matter how much or little ram I allocate to Photoshop, the probelm persists. I draw for a few minutes and then everything stops working - only in Photoshop. no problems with any other software at all.
