>>>Have a function call as tooltiptext expression. That function could check .MyTooltipText property to see if it's empty, and build it if >>so, and return it then. The upside of this is that this function won't be called until the mouse has spent the usual time above the >>control; the downside is that it adds that time to your 3-4 seconds for the 1st appearance of the tooltip.
