im running build 4.06_111ub_hd, what i meant by pal optimised was the shortcut installed on our 'brand new' catalyst, i setup a show with pixel mad and everything was working fine, turned the mac off last night and this morning no keyboard shortcut so i can get into fullscreen using the screen control but cant get out of fullscreen to shut the catalyst down or change dmx input addresses etc. i also cant turn the hud on and off. if anyone wants a copy of the show let me know,

thanks
andy
