Hi - I have AutoCAD 2000i running on Windows 2000 Service Pack 2. My input is with keyboard and CalComp DrawingBoard III. The IT guys who administer our Novell network keep a mouse hooked to the machine also, but I do not use it. My problem is that in AutoCAD about every tenth pick with the DrawingBoard cursor locks up the computer for about 3 or 4 seconds. Needless to say this slows me down quite a bit. I have played around with Control Panel settings and AutoCAD options trying to find something that affects this with no luck. Does anyone have any idea what could be causing this?
