Hi I seem to get an error when i expand a node item and the use the scroll wheel on my mouse as the node is expanding you have to be quick on the wheel mouse, only happens on list that actually long enough to give you a scroll bar in the tree control.
The Error is basically a white box appears and stays in one position over the node items , items are there just behind small white box. Only solution i had is the set the openduration to 0 seems to work Anybody had this before?
