I have a new system and when I try to run my favorite old game on it, BZ, the menu system is all black. I can see the cursor and I remember that the exit button is on the top left and the exit button works. If I press it, the game shuts down fine, and I can see the green exit picture of a tank.... as if all is well just for a split second while it shuts down. I have no idea what to make of this. Back in the day I could easily problem solve a lot of graphics issues with this game, but I don't know what to do this time.
