When shift-clicking in a CMYK image to create fixed sample points, transparent magenta-colored rectangles appeared over the image, centered on the clicked point and extending back to the top-left corner. I was giving a training course and only had time to save a screenshot, not a copy of the affected image. Only solution was to re-start Photoshop.

Looks a lot like a video driver bug, most likely openGL related.

Might possibly even be the physical hardware problem (the graphics card may be bad).

I would try the 'Troubleshooting' section of this document: GPU and OpenGL support | Photoshop CS4, CS5

Sorry for the delayed response. Didn't think anyone was listening.
I'm on a 2007 MBP with an NVIDIA GeForce 8600M GT that I just discovered Apple has known to have problems. Do you know if this card should provide openGL support for Photoshop CS5 and CS6? I can't seem to activate openGL.
Thanks,
Don

Yeah. That's a supported card. What version of Photoshop are you running? What OS are you running?

CS5.
OS 10.6.8

The local genius bar fixed the lack of openGL by resetting PRAM on my (old but otherwise adequate) MBP 2007. Got home and the problem returned.

Would buy a new MBP but Lion i s non-option for me. Every week i run four apps that rely on Rosetta - Profilemaker, MeasureTool, MonacoProfiler and i1Share.

Looking for a brand new MBP with antiglare and Snow Leopard.
