I frequent a great 3D VR program called Second Life.  If I use any of the CursorFX skinned cursor sets, the cursors blink crazily like they are short-circuiting.  This happens only when I move the cursor into the Second Life window.  When the cursor is moved outside the SL window, everything is cool.  The only way I can resolve this is to switch to Windows Default Cursor settings.  Which is no big deal.  I know this has something to do with something called interpretation of transparent layers or something, but have no idea if the phenom is correctible.  Just curious.  Anyone?
