Mouse Over Pop-up Edit Boxes
You can associate mouse over pop-up pages with edit boxes. The pop-up page appears when you hover your mouse over any edit box that is pop-up enabled. You can identify edit boxes with mouse over pop-up pages associated with them because these edit boxes are both display-only and they appear with a dashed line beneath the control.
You can configure edit boxes to display pop-up pages at runtime by configuring properties on the Use tab at design time.
