i need to use functions keys inside dosbox or dosbox-x and I can not get them to work. I have an older 16 bit program that used F1 F2 F9 And F10 for different support functions and the seems to run fine, but I can not get the function keys to work. Nothing I do inside key mappers has worked. I either do not understand how it works, or it will not allow my program to get function key input. Any suggestions or help would be appreciated. Ray
