Mark, et al.

Ah. So it is not the latest and greatest idea.

And not updating unless the value has changed does indeed make it less ugly. Nice one.

But why does setting it to empty matter as regards updating the property? The property changes correctly, as I said, it just does not update the display. Anyway, I think I will add a note to the dictionary.

Thanks everyone.


(I didn't test this one, but this is how I always do it)

Hi Craig,

All other solutions posted so far will cause the tooltip to flash in an ugly 
way. Here's how to do it:

on mouseMove
  put (the value of the mouseLine)/36 into myNewTip
  if the tooltip of me is not myNewTip then
    set the tooltip of me to empty
    set the toolTip of me to myNewTip
  end if
end mouseMove

(I didn't test this one, but this is how I always do it)

Best regards,
