Hi.
I started using jaws, but I cant play ahc. what I must do?

Stop using it.

More seriously, the problem is probably the fact Jaws blocks the arrow keys the game needs to use. So what you can do is remap them by editing the game's configuration file, however I don't think you can fully avoid using arrows. The best thing if you really want to play with Jaws for some reason is to play with a gamepad or a Joystick. Alternatively, you could disable Jaws in the game and play with Sapi. Creating a profile that puts Jaws to sleep while in AHC's window is also an option.

here are the instructions to play AHC with JAWS:
-download this jkm file:

-go to run, type appdata, go to roaming\freedom scientific\jaws\your version\settings\enu and copy it there.
-after you're done, open AHC, hit insert+v, and type "typing" in the search box, down arrow, and press space until you set the typing echo to none and hit ok.
you're all set! have fun!

thanks. gamepad is hard to use with this game.
