downloaded the beta demo of A7 though having problems getting it to work properly, everything works fine without errors but go to build then run and all i see is a black screen in window mode and full screen modes, the debug log reports no errors either and there cant be a problem with my graphics card as old a6 still functions.

anyone know whats up ?

The reason for a black screen is usually that there's nothing on the screen.

Start with the lite-C tutorial. If one of the lessons does not work please post here again with a description of the problem you encountered. See "How to report a bug" at the beginning of this forum.
