What PS version. How much ram? What percent allocated to PS? Should be 50-60%.
Open Event Log in OS to see crash report. Suspect you do not have enough resources to run multiple programs.
I often have PS, AI InD and maybe even Word, or WordPerfect open on my XP-Pro SP3 computer w/ 4GB RAM. Now, I have a very large Windows Virtual Memory Page File (10GB), and my PS Scratch Disks are set to two almost empty 1TB HDD's.
I do similar with Adobe Premiere Pro, Encore, Photoshop, Illustrator and also Word, or WordPerfect, and have never had one crash, even if I also open Adobe After Effects.
My guess is that you are having a resources issue, and the answers to Curt's questions might well hold the clue.
Your system info is far too vague. Provide exact one as well as crash info.
As the otehrs suggested already, you may be simply running out of resources on a rather weak system, but we cannot know for certain...
thank you all for the responses.
we are talking about photoshop and indesign cs5
computer has 2GB of ram (it's maxed out)
70% is allocated to photoshop
the computer is an older machine that just recently got a hard drive update to 1TB with a new graphics card as well. before the updating of the software through adobe's software manager (i can't recall what it's called right now), they were running fine. i was able to have both of them open at the same time. were the updates that drastic that now i can't have both open? would a reinstall help or is this really a case of not enough resources?
the crash report says nothing about resources....it's just the general windows error: "photoshop (or indesign) encountered a problem and had to close. we're sorry for the inconvenience."
Two gigs of ram is really marginal for todays software. With 70% of resources to PS you are probably starving computer to do anything else.
Time to save for a new computer. XP days are over and a 8gig of RAM is now recommended. Probably CS7 will not support XP.
I'm not confident it's entirely a resource issue.
I'm encountering the same problem.
Previously I did not have fireworks installed. Installed today, and immediately there are some sorts of conflicts that cause InDesign's CPU utilization to spike and hang.
I'm running Win8 on 8 GB ram.
