I bought CMBB also, unfortunately the sound doesn't work, i turned in a support ticket with GOG. It's probably a .dll file issue. I did get it to stretch to full screen. When the screen resolution choice came up at game start i chose the 1440x1020, i think that was the one.Then in the CMBB folder there is a utility called dxcfg, start that and you can adjust some video settings. Here's what works for me to get it to go full screen. I think disabling the aspect ratio and choosing windowed mode is what did it.
