Air Mouse fails typing some symbols in Firefox

Hi, I have problem using Air Mouse with Firefox. I can easily type in page line the web address in English. But whenever I get into page line to type symbols starting from ( to " including @ they do not appear on ATV. Also Russian layout is not typed on ATV at all. Does anyone else have the same problem?

Have same problem, many characters do NOT show
does anyone answer this freaking forum,
think I go in the back yard and yell, probably get an answer sooner.
