Ok, gonna try to reset my PRAM. I'll have to find a USB keyboard because my wireless one won't work. Is there any way to reset the PRAM w/o having to press the keys as per the instructions you provided? Probably not, but I figured I'd ask before I go looking for a keyboard...thanks!
Now, i'm thinking back to last night when I was editing a project using FCP X. My activity monitor was showing that my RAM was pretty much all being used with only fcp x running. That usually doesn't happen. I upgraded to 16gb of ram a few months ago...since I did that, fcp x has been working fantastically. Mast night was the first sign that something was up.
