HTC Wing / P4350 (Herald)

While playing with my store's demo over the weekend I found that if I started the IM program that it would stop responding if I tried to close it using the task manager. I figured out if you go into the task manager there is an option for running processes, just like on the task manager on a PC, and you can close it that way.

I'm not sure if this is just an issue with the demo we have or if it's an issue with all Wing's. We shall have to wait and see I guess.
