Games not displaying properly after MaLa/MAME reinstall

[javeryh]

I posted this on the Software forum but maybe it's a monitor related thing so here goes: 

I just recompiled MAME 0119u3 and installed MaLa 1.04.  After setting everything up and launching a game, everything appears very pixelated like the wrong resolution is being used or something.  The snaps behind the game list all look fine as does the FE display generally - the problem is when I launch a game.  Is there a setting I could have inadvertantly triggered that would be causing this?  All of the games played fine before I updated.

Any help would be great - I finally decided to update my cocktail cabinet with MaLa instead of GameLauncher because it's way more user-friendly.  I'm even thinking about getting an iPac4 and swapping out my iPac2 so I can take advantage of the game rotation features and stuff.  Anyway, I really want to get everything to display properly before this weekend.  Oh, I have a Happ Vision Pro 19" Shelf Mount VGA/SVGA Monitor (49-1337-VP2LG).

Thanks!!
