Ok, I have tried all combinations of things I can think of:

1. Letting PmMemCreateMC() calloc its own memory instead of creating the shared memory object.

2. Used Pg_IMAGE_PALETTE_BYTE instead of Pg_IMAGE_DIRECT_888.

3. Adding call to PgDrawPhImagemx() after PmMemFlush().

Nothing works .... just get the window and a blank button.

Does off screen drawing require a special graphics driver or setting ie. 8 bit vs 16 vs 32 bit color?

Thanks
