Hi,

Sometimes when I click very near the edge of a virtual tree (dockstyle fill, with a splitter at its side), I get a null reference exception (object reference not set to an instance of an object) and with the stack trace presented below.

I get the feeling that somehow the widget control expects a reference to the virtual tree, but instead a null is passed, as somehow the mouse position is too close to the side. It doesn't happen all the time (but often enough), so debugging may be quite a task. Therefore I would like to know if the problem has been observed before, and what the widgetControl.OnClick expects at this point.

Thanks in advance,

Kees
