Or i think i have found an way to do it here on kongregate.. just drag the frame gray part out of the "window"
press the blue part and drag the gray part untill you dont se it then let go.. it should be erased then
Its something wrong on kongregate.. when i made this game everything worked perfect but when i uploaded it on kongregate it dosent work.. i will conact them and see if they can fix the problem.
