Chris,
I didn't realize ToolTipText_Access triggered each time the tip pops up. But it's too darn hard IMHO because it requires another object and a timer with more code to turn the tip off after awhile like happens with the default tooltip. MouseMovedOut will make it much more feasible.
>Using a tooltiptext_access method gives you all the control you need. Pass an reference of the current object. When that reference is not equal to sys(1270), release your tooltip. There are some other complexities, but it is doable.
