How to hilite a checkbox with send mouseup?

[Tiemo Hollmann TB]

Hello,

when sending:  send "mouseup" to btn "test" the button gets the mouseUp
command, but doesn't hilite, though it's property Autohilite is true.

Do I really have to set additionally the hilite of that button by script?

I also have "pass mouseUp" in the buttons mouseUp handler and I am getting
"exit" as the result in the message box

What am I missing? Why do I get "exit" in the message box?

Thanks

Tiemo
