We have 5 systems that recently were upgraded from Photoshop CS to the CS2 version. They are running 2.4Ghz Celeron processors with Windows XP SP1, 680MB RAM. Based on the information from Adobe our computers match all the requirements except for the processor which lists Intel Xeon, Xeon Dual, Centrino, Pentium class III or 4. Does anyone have an opinion on the Celeron processors with the newer Photoshop software? Our users are running into problems of the software locking up on them and blank windows where you can tell there are buttons but not sure what they are for. I hope I have supplied enough information, if not, please let me know.
