Hi there I also have this problem from a clean install using the proprietary ATI drivers on a dell studio 17 laptop with a Radeon Mobility 5650. The cursor gets stuck in the drag position when I try and drag and drop a file out of an archive and into the stock file manager. All the applications continue to operate but no key presses or even the power off button seem to register. Would you like me to post a log output as this is an easily reproducible error?

I had this problem too almost cost me alot of server loss
so if it happens u can save yourself by doing this

pres and hold CTRL+ALT+F6
then login
then type the following commands:

sudo -s
ps -U [your username]

then look for something like
[pid] ? 00:00:02 File_Roller

then:
kill [pid]

of File_Roller

then press
CTRL + ALT + F7

your welcome:P
