Little black out here need help with a treemenu in director 8.5?

[keitai]

Hi all,

Need some help with a vertical treemenu in director 8.5.

It is as follows:

Let's say i got 8 main navButtons.
Then on mouseDown button 1 my menu collapse and you see a bg img with subnav buttons.

Right now i got


on mouseUp
if the doubleClick then exit
startTimer
repeat while the timer < 20
if the mouseDown then
cursor 280
sprite(12).visible=false
sprite(16).visible=false
sprite(17).visible=false
sprite(18).visible=false
sprite(19).visible=false
exit
end if
end repeat
sprite(12).visible=true
sprite(16).visible=true
sprite(17).visible=true
sprite(18).visible=true
sprite(19).visible=true
end mouseUp

on mouseLeave

end

So doubleClick closes the collapse img.

But i want to have it on the second mouse down.

Recap: first onMouseDown ->collapse second onMouseDown de-collapse

Any tips, tutorials???

Kind regards
