When I'm in Tree Mode my mouse pointer suddenly sticks and refuses to be unstuck unless I get out of that mode (if I can). There seems to be neither rhyme nor reason for this happening - I think all is fine and happily pottering around in Tree and suddenly "it" happens.
I'm using an iMac and Firefox. At first I thought the problem was with the Bluetooth mac mouse so I unplugged that and tried a usb mouse but had the same result. It's driving me slightly insane....
