Leave ultramap up in the background while you're running mala.
When browsing through your list, alt-tab over to ultramap and move the stick around. It should be in 4-way mode, and you can tell if you can't get the little cursor to go into the diagonals.
Then alt-tab back to mala and launch a game (any game, but space harrier will do) then with the game running pop back over to ultra-map and see what it's configured to then. If it's not what it should be (you could look at the xml for that game) then either the plugin isn't working, or something has told it the wrong config map to load. Try a few other games to check to see if any of them are getting programmed properly and report back here.
