Hi Chris,
you're answer came close, I modified it a bit to be more accurate. The things I've done are:
move the location reading into the event structure (it's better correlated, in the time-out you had a lag of 10 ms.)
set the timeout to -1 when the mouse is inside the pane (mouse-enter and mouse-leave events)
Then I'd thought wouldn't it be nice if this code can be a sub-vi called on a mouse-down event?
That worked BUT in the subvi there are no events generated on the pane class, althought dynamic registration worked I can't seem to trigger events...
So the sub-vi works but only because of the time-out case....
Sorry but i can't add attachments
