Foster,
I have been researching this problem all over the Internet. The answer is always the same: it's the user's computer, the computer has not enough RAM, send us your logs, here are a few fixes and good luck. From what I've found, especially PS has an issue of not unloading all memory once it's done w/ a particular task, but in general please explain to me why the SAME PSD file takes up 1.2 GB of RAM on PS CC 2014 and less than 500 MB on CS5? I could run this either as a 32 bit or 64 bit version, it would *still* crash. If y'all were able to actually fix this, you would already have. The only "fix" for me is a software that actually *works*. CS5.1 is completely stable. Virtually *NO* crashing at all, saves take only a few seconds and I'm never stuck on a PSD file that won't save, or an "appcrash".
I could send you all the logs I have, just like IPX has - and all the numerous other people. You would still not be able to help me. But if you truly care, make sure that the next release is actually a working model.
OK, I'm done now.
Thanks.
