I updated mamewah to 1.61 (from 1.5) recently, and I'm having trouble with Duke Nukem Manhattan Project now.
It opens correctly, it plays alright, but it seems that mamewah retains simultaneous focus while playing (I'll cycle through gamelists, open other games, or multiple instances of DN etc). This doesn't happen with any other games, PC or otherwise, and seems to be new to this version of mamewah (or maybe one in between 1.5 and 1.61). I assume I'm doing something wrong, any pointers?
[Edit]: More info in bottom-most post.
