Verizon TP2 sure gets hot left connected to USB

[WBFAir]

Hello all

I've notice that if I leave my Verizon TP2 connected to the PC via the USB connector for a long time it will get really warm after a while once the battery is finally fully charged.

Its almost like what ever is recharging the battery in this mode is not shutting down once its fully charged.

So far I have not found this to be the case when its plugged into the wall charger.

Is this normal or may I have perhaps funked something up with all the registry add-ons I've installed.

Thanks
