I can reproduce, but argh, I can't find anything to do about it.
The only ways I can find to fix it also make the entire page swipe-able, which ruins any games using touch control (as you swipe the whole canvas slides up and down). So it seems we're either trapped between either broken form controls or the entire canvas swiping.
Don't know how to fix this for now...
Edit: would a workaround like an action "enable form controls" followed by "disable form controls" be acceptable? If you need text entry on a menu screen you could enable form controls, but then disable them and return to game mode for the game control...Ashley2012-01-30 23:28:54
