[HS] will HS on Wincows Mobile change orientation?

On my new T-Mobile HTC HD2, HandyShopper seems to run quite well (2 days new), but it does not change orientation when I turn the phone sideways, nor can I find any place in HS or Win mobile to tell it to turn.

My old Palm TX had a software button to change orientation and HS did fine with that.

Does anyone know for sure if it will turn -- and how to do it -- or if it won't turn?

Thank you kindly.
