I a TsTreeViewEx contains an item that is wider than the width of the TsTreeViewEx will be able to show, the item disappears all together, when the mouse cursor mover on it. Only selecting another item will reshow the offending line.
This is the neutral view:

This is the view when the mouse hovers above it:

It looks like this when the item is clicked and expanded:

Hovering above another item does not reshow the offending line, only selecting another item will do that:

If SkinManager is not active, this problem does not occur.
