That's a good start. I'll try that today.

No, it was always the MouseMove, when it called HitTest. I'll run a series of tests over this. Thanks for the info - even without this version issue, the TreeView was always somewhat tricky, so I just had to get as much knowledge from others before digging into it.

[later]
Found it - it says my old TreeView is 5.0 SP2, and my VFP is 5.0 (no SP - I just wander what installed it and when). I've tried using the TVw 6.0 in VFP5.0, no good. Works, sort of, but doesn't react to clicks and keys. Funny, though, the TVw 5.0SP2 works nice in VFP6... you're right, no need to get started on this, we'd suffocate the audience.

I think I'll just reinstall the old TVw and keep the 6.0 for VFP6 alone, until I obtain the SP2 for the VFP5.
