I'm getting focus problems too. I'm running Windows 7 Ultimate, and I think the focus problem happens both when switching to Mame and when exiting a game to go back to the Mala. Problem is, I'm never around to see the bug happen. The game is set up in the kitchen at my work, and whenever I come by, it's locked up. Since Win7 has a lot of hooks in it for various programs and background services to run, it's not a surprise (with how badly software is written today) (I work at Microsoft) that something else tries to grab the focus. Things are complicated now. There needs to be a background process running all the time that says "If mame is running, IT gets the focus" "If mame is not running and Mala is running, Mala needs the focus" "Everybody else, you can all go **** yourselves, you're not getting the focus, ever". :-)
I'd like to beta-test some new mala versions too.
In my mala installation, by the way, it is ABSOLUTELY barebones. Nothing but the bare installation. No videos, no attract sounds, no layouts, nothing extra.
PS: Everybody here at work does NOT like Mala's feature to show the extra game info, or the ability from the UI to allow filtering of the games or removing games from the list. All I, the adminstrator, of the box, want is the ability to select from one of a variety of games, then run said game. Is there source code for Mala so I can compile it and remove the extra stuff?
