>Seemed to work OK with listbox. I think the bug is with ComboBox. From MSFT KB:
>
>1.PRB: Combo Box ItemTips Prevents Selection and DisplayValue: When a combo box that has a narrow column width and ItemTips property is set to true (.T.), the ItemTips window prevents the selection of a choice from the list of values in the combo box.
>
>2.PRB: ItemTips = .T. Causes Error When in Private DataSession: In Visual FoxPro 5.x, the Listbox control with the ItemTips property set to .T. - True causes a Cannot access the selected table error when the DataSession property of the Form is set to 2 - Private Data Session.

These look accurate...when I first found bugs, there wasn't any KB article yet, but now it's official! Hope it's fixed in 6.0...
