It seems that the release version of Flash Player 10.1.52.14 that comes with Flash Builder 4 has minor mouse bug on Mac OS X 10.6.3.
Once the cursor changes to 'hand' on hovering, it does NOT return to default arrow on roll out.
One a positive side, scrolling with the mouse wheel on Mac is finally working! Many thanks to FP team.
I confirm this bug in FP 10.1.52.14 on OSX. It should be solved
