After PgSetVideoMode() all other Photon calls return an errors.   
While writing tests for the different blittings, I've found that after PgSetVideoMode() function all other Photon 
functions are failing.

In the attachment the original gf-ph-3d demo, where I've added a mode switch in the abmain.c before the main loop. It 
switches to the current active video mode (resolution, bit depth and refresh rate are the same).

Why this happen ?

IIRC, on all mode switches, the surfaces get torn down ... because the
format has possibly changed.  Take a look at services/graphics/main.c

I've put a modeswitch call to the beginning of this testcase, where surfaces still not created. After modeswitch, for 
example, PgGetVideoModeList() function returns -1 on each call.

what version are you using?
