I am always getting this error, when dragging a node in my treeview. I reported this error to Novell, but they say, that they can't reproduce it. I get this Error with Mono 2.4 (both windows and Ubuntu 8.04). Is anybody there that can reproduce this error? You can get my application at https://sourceforge.net/project/showfiles.php?group_id=257087&package_id=315752&release_id=675230
