I've encountered a little glitch recently. I'm on an older G5, running OS X 10.4.11.

I've experienced this error in nearly every program I run, from Adobe products to Mac Mail, to web browsers.

When scrolling down to select a file to open or attach, the program freezes, I get the ol' wheel of death and a "program not responding" error. Force quit doesn't even work to clear the program.

Any thoughts as to what might be going on and what the fix might be?
