Drawing area display lags behind mouse movement

Hi All,

I'm running DraftSight on a lenovo ThinkPad T410.

DraftSight Version v1R4 x64

Windows 7 Enterprise

Intel HD Graphics driver, 8.15.10.2202

8 GB RAM

Intel Core i5, M540 processor, 2.53 GHz

When I move the mouse on the menus, everything is fine (fast/smooth).  As soon as I move the mouse into the drawing screen, the movement is slow and choppy.  I've looked for a setting in the Options to turn on or off hardware acceleration which is normally a cause of display problems, but can't find anything.

Is anybody else having this problem?

Thanks!
