Is this PS3 or CS3?
OS and computer resources please.
So.... use a crystal ball perhaps it can give you some vision. Without any information about your ps3 past history it hard to guess why. PS3 is so old early 1990 what OS are you using.
Amen to what the others said. no point in even trying to unriddle this as long as we can't even be sure what version of PS you mean.
Another little mystery to solve.
The use of the term "quitting" implies a Mac user. A PC user would more likely say "crashing".
I've noticed that Mac users are often imprecise, I guess because they're generally not required to know as much detail to be able to use their systems... In this case "P3" and "PS3" most likely mean Photoshop CS3. In that case I don't think we can imply much about what model/generation Mac Janet is using.
Unfortunately, given these assumptions and the absence of the more detailed info requested by those above, about the only advice I can give are these things:
- Try clearing your Photoshop preferences to defaults.
- Run diagnostics on your computer.
- Please provide more detail on the environment in which you're working and what you're doing.
