Yeah, what is the magnifying glass? It seems like it could be a cooL feature if I knew how to use it. Also, a mouse cursor appears occasionally; how do I use that?!

Also, just use the soft reset button. It's less effort than taking your battery out.

edit: I haven't seen lockups for any of the reasons that you have listed, though. When I see the magnifying glass tool, it just goes away and everything's still normal. Since there aren't more reports, I'd guess that it has to do with software that you've installed.
