Running 0.73 under Windows 7 and am having two problems.

First is the more critical one. At first, DosBox lost sound after I ran it for 1-3 times. This I could fix by rebooting my computer, after which the problem would return after another 1-3 runs. Now however, now even rebooting seems to help and I'm not getting any sound whatsoever despite not touching the configurations.

Another problem is that, in full screen mode, the picture is positioned in the bottom of the screen, leaving a huge black block in the top.
