Digging back through UT messages, I found my own message from late nineties where I have found some differences in behavior between MSComctlLib.TreeCtrl.2 and COMCTL.TreeCtrl.1 - and I have never had problems with the latter. It also calls .hittest() and, after checking it, yes it still works OK. And the problematic class uses the MSComctlLib.TreeCtrl.2, of course.

The problem was that if you click outside of the text, it highlights the whole row, but doesn't change the selected node, so both the freshly clicked row and the row with the selected node appear selected, but no nodeclick() is fired.

>I tried with a clean treeview, no APIs, and it doesn't even register a mouseDown or MouseMove if it's over a blank space. The one with APIs does, but in it most of the .hitTest() calls end with an error - for some values it's OK, for some it says "invalid type or count". For a while I thought it's because these parameters are defined as Single (it's a VB6 control anyway), and some of the values for twips per pixel came out as currency(!). I tried to cast them as integer or n(8,0), but no dice.

"I tried with a clean treeview, no APIs, and it doesn't even register a mouseDown or MouseMove if it's over a blank space."
So does that mean the code I sent is broken there? (or you didn't run at all:)
"it highlights the whole row" - reminds FullRowSelect = .t.
Hard case:( -and not using mdot maybe the culprit, but it's you, no.
