The object is currently in use elsewhere?

Hi all, has anyone seen this exception in Visual C# before?

I have a GUI that has a number of timers on it (ie a clock). When I try and move the form
or do some other coding on the movement of the clock I get that error.

I am using the graphics class to repaint.

the error is:

An unhandled exception of type 'System.InvalidOperationException' occured in
system.drawing.dll

Additional information: The object is currently in use elsewhere.

I have done some searching and Microsoft has it as a bug for the PCTABLET. I also
see that someone fixed it by changing the screen's properties/settings/advanced/trouble
shooting acceleration control.

Any help appreciated.

with regards
James
