Nah (saw your post on that), using the packaged charger. It does it while charging or not.
It's the stock HTC weather widget (small icon version), taskiller did this, and another icon that I can't think of at the moment does it. All three just open on long press without the option to move, delete, etc. I haven't seen any way through the settings or other menus to remove apps/widgets/icons from a list format.
