is this a bug or a misconfiguration?

good folk,

statemnt of 'problem'

mouse freezes upon logging out of kde (2.2.2), both as user and as root.
after kde cleans up after itself, the 'X' cursor appears in centre of 
screen, but is also frozen.  when the login screen appears, the 'X' cursor 
turns into a regular mouse cursor, but still does not move.
keyboard functions normally.
restarting the X server (alt-E) restores mouse movement.

this has been happening since day one of kde working.  occurs every time, 
very reproducible.

7600 with g3 sonnet card.

anyone seen this before?  ideas?
