I have an Apple Magic Mouse and I use the BetterTouchTool utility to
allow me to tap instead of clicking.
I always scroll by swiping, so I hadn't noticed the scroll bar
problem, but I can see it now I test for it.
I don't have any problem clicking a button with just a mouseUp
handler, but if I have a mouseDown handler that does something, then a
lot of the time it will miss the mouseUp message.
I wonder is this what is happening in the scroll bars too?
P.S. I will add these thoughts to the bug report.
