Duplicate mouse cursor appears (but doesn't move) on second monitor
I have a Mac Pro with the ATI XT1900 video card and 2 Dell 2407WFP LCD monitors attached via DVI.
When I'm using an application, such as a web browser, and the cursor changes state (like the black arrow with spinning wheel in corner) a duplicate of this cursor state appears on my second monitor, on the left-hand side of the screen.
This cursor DOES NOT MOVE, but does animate, and will not disappear unless I move my "live" cursor over to the second monitor, which I imagine causes OS X to "refresh" the position of the cursor. It realizes the duplicate shouldn't be there and it vanishes. The second cursor seems to appear only when the primary live cursor changes state, as in the black arrow becoming a black arrow with spinning wheel in the corner, etc.
This is not a duplicate cursor due to having Displays set up to mirror one another. The second cursor doesn't move.
This has happened in more than one software application, so it appears to be some sort of display driver error at the system level.
Anyone else experience this or have a way to fix it? There have been several Apple Updates to OS X since this problem first started happening (on day 1 with the Mac Pro) and it has not been resolved.
