#35 Tree updateUI throwing NullPointerException
When creating a folder, the tree is not updated. Instead, the tree.updateUI statement throws NullPointerException.
Resizing the tree does not update anything, but adding new files does.
This happens at least under Windows Vista. Not sure if it happens under Linux.
