I was just making a few changes to the chem warrior to make it beta (grey hazmat and a litle nod logo) so i click to save (i understand tot make a 2nd copy) so i click the pixel format ( DXT1) and where it says ok or save w/e its greyed out !! *sory for splling mistakes im too tired*

Merge all the layers and try. or merge all the layers, select all, copy, open a new document paste it in and try saving it again.
It grays out for many reasons, most common being the dimensions of the document are off (not 128x128, 256x256 etc)

Ahh right well thanks mate
