Okay, weird-ass problem: Preview randomly doesn't behave correctly anymore. PDFs open fine, but when I try to use Preview to open a series of JPG images (or even a single JPG image) Preview doesn't respond. If I click on the desktop to switch to Finder and then click on Preview again, the first image in the series opens, but Preview's controls are non-responsive (drawer doesn't open, can't page up or page down, can't zoom in/zoom out, can't scroll, etc.). I've tried deleting the plist but that didn't help, and rebooting had no effect either. I might also add that I haven't done anything to my system between when this worked (this morning) and later today when it suddenly didn't work. Any ideas? EDIT: Not sure it's important, but I'm running OS X 10.3.8, and have been since it came outPreview's troubles started just today, well after the upgrade. So there's that, for what it's worth.
