>I’m toying around with Mabry’s Tree view control and found that after I select an item on the tree I cannot select any text box on the form.

Have you purchased the control, or are you looking at the demo? If the latter, you might want to check out http://www.exontrol.com/sg.jsp?content=products/extree. The author of the Mabry control started his own business last year and has a TreeView control that he _assures_ me is superior *g*.
