not sure how clever it is, but this does the trick.

i like MIB's better of course...

Thanks guys. Ending up using this as I need separate events for up and down. I was fooling around with various ways of doing this using mousestate but I couldn't get the timing right. Using gate sorts that out.

of course you could always fake it with ubutton as well...

another way to do it with ubutton and textbutton in toggle mode:

Would be nice perhaps if textbutton just had the same outlets that ubutton does to avoid this annoyance...

Requested noted, but ubutton doesn't do everything that textbutton does either, they are just different objects. Welcome to the world of UI design. One person's annoyance is another person's fantasy and vice versa.
