Hi.

I've found a strange behaviour with all of my computers.

I have a USB-memory, with the new U3 stuff on it.
If I insert this stick while running Mediamonkey, the whole computer hangs until I remove the stick again.
Inserting the stick without running MM works fine.

Also, inserting another USB, that's not running U3, works fine both with and without running Mediamonkey.
This leads me to think that the problem has something to do with the U3-standard and Mediamonkey.

Just thought I'd let you guys know.
