Seeing this error when working in Photoshop CS5:
“application error 0x00000078: memory could not be read. Instruction at 0x6963932b”
And then it gives the option to cancel or hit Okay. Both options kick me out of the application (without saving my work, of course). Here are my system specs:
Adobe Photoshop Version: 12.0.3
Operating System: Windows XP 32-bit
System architecture: Intel CPU Family:15, Model:4, Stepping:8 with MMX, SSE Integer, SSE FP, SSE2, SSE3
Physical processor count: 4
Processor speed: 2793 MHz
Built-in memory: 3326 MB
Free memory: 2343 MB
Memory available to Photoshop: 1689 MB
Video Card: NVIDIA Quadro FX 1400
A crash like that is often the fault of one of two things:
1. A driver bug (e.g., your video driver).
2. A bug in a 3rd party plug-in.
I notice you have a nVidia Quadro card. There have been a number of reports on this forum lately about Quadro drivers not working all that well with Photoshop, and your particular card is quite old. A few years ago I personally struggled with a nVidia Quadro 3400 (closely related to yours) and never was able to stabilize things until I just took it out and bought an ATI card.
NVidia appears to be fond of releasing new drivers for old cards that just don't work.
But before swapping out your card, it might not be a bad idea to visit nVidia.com and get their latest driver.
Also, you might find that turning off OpenGL in Photoshop's Edit - Preferences - Performance menu will work around the problem, though you will lose a few features.
