PocketFrog - backbuffer

[NokFrt]

Hello,
I'm new to PocketPC programming. I've chosen PocketFrog for making a PocketPC port of our Symbian Series60 game ATOMIX.

I've got one small question:

Is it necessary to blit all the scene every frame or can I be sure that the content of backbuffer is unchanged since the previous frame?

Thanks

Tomas

I think you can assume the buffer is unchanged unless your game loses focus due to a pop-up window (low battery, etc.).

Write your own GameSuspend() and GameResume() functions to force your app to redraw the entire screen.

Someone correct me if I'm wrong.
