I just noticed what seems to be a problem in the tree control. I was trying the tree control reference example and with the tree showing a directory I was testing to see whether the tree remembered the collapsed/ uncollapsed state of lower level nodes when the top level node was uncollapsed -> collapsed -> uncollapsed. I found the lower level plus/minus icon then showed as uncollapsed (minus) but the node wasn't actually expanded.
i.e.
start with tree all collapsed
use right arrow key to expand first level
use down arrow key to go to first child
use right arrow key to expand first child
use up arrow key to go back to root node
use left arrow key to collapse root node
use right arrow key to expand root node

now you should see the problem where the first child node has a minus icon but is uncollapsed. Sometimes the problem doesn't appear the first time.
