I'm afraid I've found some serious trouble with DOSBox v0.70: Some sound setup programs don't seem to like it. With both "Indycar Racing" and "Rally Championship" I've had to configure the sound drivers running the INSTALL / SETUP programs through VDMS. The programs seem to work at first under DOSBox, but then they behave as if I was stepping on the keyboard, moving the menus too fast to select anything properly. I've tried setting cycles to 3000 manually, but the problem persists, and since I've had no problem setting the sound drivers in previous versions of DOSBox, I assume it's a bug introduced in v0.70.
