This may be about and addressed somewhere but from searching fullscreen and blackscreen I didn't find it. The game seems to run fine. I can even run Ender's client if I use the 32 bit edition. The 64 just refuses to start. Anyway if I switch to fullscreen my screen goes black. Not sure of any way out of it other then tabbing out and forcing the client to close.
Sorry if this is common knowledge but I would really like to be able to run the game fullscreen.
