I run a full inventory minus 8 spaces when I cow/mf. I right click the prime charm and hold ctrl+left click to move unidentified stuff to the prime charm/cube to free up in space and just identify them all in the prime charm/cube via Cain when I am done mfing to save time. Sometimes (more than I wish) I get a crash to desktop error when I move my unidentified items to the prime charm/cube using the ctrl+left click.
