Reader blocks Win 7 Task bar from Un-hidding

Hi there,

When I have a Reader pdf open and selected that extends beyond the bottom of the screen, I'm unable to bring the mouse cursor to the bottom of the screen in order to "un-hide" the Windows Task Bar.  This is not the case for other applications.  I did not see any options to change this in Edit > Preferences.  I'm using Windows 7 Professional and Reader 11.0.2.

Thanks,

Kirk
