I programmed an MX350 to control a Q-Media Media Center. The media center is Windows based. Since there are no codes in the 350 programming booklet I learned all the codes. The problem I have encountered is when I press any button on the 350 to control the media center, it works. But if I press the same button again it won't work. I have to press a different button and then the one that I want for it to work. Does anyone know how to correct this problem?
