thanks for the suggestion. i am sure that you're right and the problem is related to a fouled-up update attempt. however, i don't think i currently have any unfinished updates. the system does not indicate any updates are pending. also, i looked at the update history and everything looks fine. so i manually ran AU and found a suggested update related to a monitor driver. i installed it, rebooted and, again, another one of these phantom folders was created. i've also turned AU off and rebooted and still get the folders. any other suggestions? can i "reset" automatic updates or something???
