   Texture disappearing when switching to fullscreen?
  For some reason when I toggle to fullscreen my texture (right now I'm only using 1 for testing) disappears and my program only renders a square in the last used glColor3f. I'm probably forgetting to reinitialize something, but I don't know what.   
  when you switch to fullscreen, your opengl context gets reset, so you must reload everything (textures, vertex buffers etc)   ;  like DanoruX saiz if u destroy the opengl rc + recreate a new one, all opengl info is lostperhaps what u can do is just resize the window so its the same size as a fullscreen
