It's face inheritance that caused the problem > with vertical movement of the button. I'd still like to understand why this happens. It sounds like a bug. You said you found some coordinates miscalculated, but didn't provide any details. Could you please provide those details, so I could try to look at that? Debugging this is notoriously hard, because the code is entered upon almost every mouse movement, so it is important for me to know which code I'm investigating to be able to set up the breakpoint conditions that avoid triggering at non-interesting moments.
