The problem with this fix is you can get a button event even if the 
button was never in the pressed state, for example press the mouse 
button on the ButtonPanel but outside of any button, then drag over to a 
button and release the mouse button.

A better fix is to not set the hover state if the button is already in 
the pressed state:
