window button in trim screen

My window button doesnt do anything when its pressed in trim mode. It lights up but nothing pops up on the screen. Is there a logical explanation for this or is it just **** up

cant remember off hand - if the manual says it should do someink and it dont - factory reset
possibly

well... you tell us... does your WINDOW button work elsewhere or not?? also, which OS are you using??

...actually, judging by the amount of posts you have, you'll probably never even come back to read the replies here [like most drive-by-mpc-newbies]... so why am i even bothering to ask?...
