>Hello everybody:

>I bring a problem to your attention about the TAB control. One of my users reported me an unusual event when she uses the tab control in a specific screen. Sometime when she change from a tab to another in the form the computer freeze (only the tab control). She can uses any other control in the screen while this happen but not the tab. The first page of this tab contains an ACTIVEX scroll bar and that works without problem.
