Shadow line remains in text editing

Hi,

I'm assuming this is a hardware issue.

When I scroll through text in a drawing the cursor 'leaves' behind an image of itself. There seem to be no other video related problems in the system.

I'm using Windows 7 64bit, SW SP2.1, Nvidia FX1800 latest certified driver installed today from the SW link. I have a Samsung widescreen monitor at 59hz connected through the DVI port.

If I enable the use software OpenGL it's fine. Is there a setting in the Nvidia section that may cure this?

This does not occur on any other old machine running XP 32bit.
