Is anyone else seeing this behavior? Every so often after the v1.5 release, when rigging a puppet, I get the "hand" tool stuck. I click on the magnifying glass, but it stays on the hand (pan) cursor icon. I can click on the other icons, and the turn blue, but the cursor icon stays on the pan tool (and it does panning). I have to exit CH and restart it to get the magnifying glass etc to work again.
Another one I got is trying to use ALT to zoom out would sometimes show the "zoom out" cursor (magnifying glass with a "-") and sometimes show the "pan" tool again.
