Ok, running Tiger on a dual G5 for a bit now with no problems, but this morning, for some reason, my screen captures aren't working. It's making the camera sound, and the processor is working (I took several rapid fire with all of CS2 open, heard the fans speed up with each one), but there is nothing--no files in documents, photos, or desktop, and a search shows no files named "Picture xx". Tried repairing permissions and rebooting, still not working. Thoughts?
