Probably what's happening is that the treeview isn't re-painted (showing the selected node) until your afterselect handler finishes. One solution to a problem like this would be to call the routine to start the child form (in your afterselect) via form.BeginInvoke. That would let your afterselect handler exit, and the treeview's paint happen, before the slow loading code even starts. J.
