Photoshop CS4 locks up when ruler tool...

I have a 24'' IMac with system 10.5.6, 2.33 GHz core 2 duo processor 4 Gig L2 Cache 3 Gig memory.

When attempting to use the measure tool photoshop locks up and the image that I am working on turns to wide bands of noise. I have to use force quit to get out.



I have no problem using the ruler tool with Photoshop CS3, however Photoshop CS4 extended locks up every time.

I tried repairing permissions -- no luck.



Any Ideas??

Have you tried trashing the Photoshop preferences?



This Adobe tech note tells you how to do that automatically or manually.

To recreate the preferences files for Photoshop, start the application while holding down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS). Then, click Yes to the message, ''Delete the Adobe Photoshop Settings file?''

I just tried that and got the same result after trashing the Photoshop preferences.

Try turning OFF OpenGL and relaunch the application. This will tell you if it's a video driver or video card issue.

Turned off OpenGL and Photoshop works!!
