The Wacom tablet is not working / the mouse pointer is jumping very fast.
To try :
* SAVE YOUR WORK
* Ask a BIOP staff to
** install all pending tablet updates using the Wacom software
** A Restart is needed
** AN ADMIN SHOULD LOG ON then after the restart - the wacom software will pop up an ACCEPT/DECLINE licence, You NEED to ACCEPT it
All should work fine now.
