App Display not right on WM6.1

[Poy]

Hi All -

my application runs fine on WM5 - (tested with HTC Tocuh)
however when i run the App on HTC HD (WM6.1) the logos are quite small and the form does not display all the controls, eg - there is like a white panel covering most of my app..!

I ran the app on the Samsung omnia (WM6.1) and everything was fine!
so i am wondering if there like a display setting that i am missing with the HTC HD!?!? I have emailed HTC Support, but they are no help...

any tips would be appreciated!!
