No, that didn't fix it. However, I've found out that setting it to no sound, it works without a hitch. Now the only question is: how do you get it to work with sound?

I've managed to get it working in both Dosbox 0.65 and 0.7, but whenever a yes/no box pops up, the game freezes. This means I can't buy anything, or even go on a mission. Anyone got a fix for this?
