Summary:
When I use my 15" MacBook Pro (running 10.6.8) to run my iMac 27-inch, Late 2009 as an external monitor, sometimes upon coming back to the iMac, the mouse cursor is missing. You can still click on things, but you have no indication of where you'll be clicking, unless there's mouseover animation.

Steps to Reproduce:
1) Connect external displayport device
2) Unplug USB keyboard (which has the USB mouse connected) from iMac
3) Attach USB keyboard to externa laptop
4) <use laptop>
5) Sleep the laptop & remove USB keyboard/mouse
6) Plug in USB keyboard/mouse back into iMac

Expected Results:
After display comes back, the mouse cursor is visible.

Actual Results:
The mouse cursor is often invisible, though it allows mouse clicks and moves.

Regression:
This did not occur in 10.6.8.

Notes:
Rebooting brings it back, but I'm not sure what simpler recovery I can do.
