You mean the (Windows) appearance or the VFP settings? That's interesting. Have yet to pay attention to that or not aware that VFP5 have "themes". But I do observe the 3D turns "flat" when the active form loses the focus to another dialog box - maybe something to do with the VTable ot Autoyield thing - will check that out later. The scrollbars definitely "themes" with XP's scrollbar, after all it's windows controls. Indents also cannot be less than 25.00 - otherwise no effect. Also FOrm.Keypreview is ineffective, so I have to put seperate codes in Form.Keypress & TV.KeyPress. But I do know that HitTest() with large values crashes the app. Other than that it's stabler than some other ActiveX controls I've used.

One nice thing about the TV is the node's "key" member. That's useful if I want to cross-reference the node to different entities. Say, I've got (1)Manager-(2)Supervisor-(3)Employee. I use "Manager_"+BINTOC(Manager.Manager_ID) for the key and "Supervis"+BINTOC(Supervisor.Supervisor_ID). Click on the node, and interpreting Node.Key tells me which record from which table to look at.
