keypressed returning odd character

hi,

 

i've bit of problem using 'the keypressed' method.

 

this in application has been working fine now, @ point user has press key, , program waits until key released.  user may have indicated choice mouse click, , following frame script has behaved needed:

 

on exitframe me

if keypressed <> "" then

    go frame

  else

    if mousedown then

      go frame

    else

      if milliseconds < gptp_endtime -- necessary pause before proceeding

        go frame

      else 

        go to  gdestframe -- gets set previous results handler

      end if

    end if -- mouse down check

  end if -- keydown check

end

 

this written on winxp, director 10.1.  however, having tried application on new laptop running win7, program hangs.  having looked it, find no key pressed, method returns ascii char 16 ('dle'), rather "".  laptop fujitsu lifebook series.  i'd grateful if might offer suggestion, , commiserate else losing hair on this.

what using keyup , keycode, in

 

on keyup

  if keycode > -1 then

  

go frame 

  else

    if mousedown then

      go frame

    else

      if milliseconds < gptp_endtime -- necessary pause before proceeding

        go frame

      else 

        go to  gdestframe -- gets set previous results handler

      end if

    end if -- mouse down check

  end if -- keyup check

end
