I updated my video adapter from an ATI Radeon 7000 AGP 64MB card to an ATI Xtasy AGP 128 MB (made by VisionTek).  Since then, the cursor (whether a Windows Default or CursorXP) disappears under some parts of programs (such as Object Dock, some context menus, some right-click menus, etc.).  I can still in some cases see the sursor well enough to tell where it is, and in others the area where it is changes color (depending upon the skin I'm using).  I have updated my drivers, the Catalyst Control Center, reloaded the standard Windows Skin as an experiment, and changed to regular Windows cursors, to no avail.  Anyone run into this problem, or otherwise have any ideas?
