If you position a TreeViewAdv window so that it has a horizontal scrollbar and then delete every node in the tree, the control goes into an infinite paint cycle (thereby eating 100% CPU).
Attached is a slightly modified version of your TreeViewAdvDragDrop example that you can use to see the problem. I simply added an event handler for keydown with delete. Build and run the example. Position the window has small as it can horizontally so that it displays a scrollbar. Delete every node.
