Hi Joel,

AFAIK, when a modeless form/dialog called from a modal form/dialog, the modal one will set itself to disabled so the modeless can act like modal. When the modal form disabled, I think it also disabled the ActiveX control in VFP form. Why the ActiveX doesn't re-enable itself, I don't know <bg>. For more info, read EnableWindow() API in MSDN

Anyway, to re-enable the TreeView, put this in TreeView Init event:

** TreeView Init event
Declare Long GetParent in User32 Long nhWnd
Declare Long IsWindowEnabled in User32 Long nhWnd
Declare Long EnableWindow in User32 Long nhWnd, Long bEnable

This.AddProperty( 'hWndParent', GetParent( This.hWnd ))

and put this in the modal form Activate event

** Form Activate event
If (IsWindowEnabled( ThisForm.oTreeView.hWndParent ) == 0)
   EnableWindow( ThisForm.oTreeView.hWndParent, .T. )
endif
