I only use tooltips on a GET or similar control very rarely and then only when the user either enters invalid or questionable data. Having a tooltip popup every time a control gets focus would be very irritating after the first couple of times.
Antonio, one thing that would be useful is to have a tooltip class that is exported so we could replace it or easily control it. The current oTooltip used in TWindow is a static var so we can't access it. I have written a TTooltip class if you would like a copy. I created this to implement the procedures described in the above paragraph.
