Bit of an update.

Ran SFC /SCANNOW, but came back fine, no integrity violations reported. Also updated the drivers to Catalyst 10.6.

Thanks for the idea about the second monitor fseal. I highly doubt it's that, but it'll eliminate one more variable.

Unfortunately I seem to have run into an oddball glitch without a quick solution. Without being able to reproduce it, now it's just a waiting game to see if it shows up again. I should also mention that since it's quite infrequent and easily fixed, it's not really annoying, more just a curiosity and challenge to fix. If anything changes, I'll let you know.

Thanks again everyone.
