"HW rulez" mod (add-on) for HoMM3.

Hey everyone, I'm having an issue with version 1.38.2 (downloaded using the button from the online lobby): when two heroes meet, the left/right arrow keys on the keyboard don't work to exit the control window. They should duplicate the functionality of the buttons located in the bottom corners of the window; the buttons work, but the keys don't.
Has anyone else encountered this?
