I'm having trouble with these blips in the running of the emulator even before a program is running. These manifest themselves as micro interruptions in the music or sound (obviously only when a game is running) or even a brief horizontal line across the screen, as though the video card was interrupted in mid-refresh!
I've been through http://www.dosbox.com/wiki/Performance but the solutions don't work, and sometimes even create new problems.
I'm running Ubuntu 10.04 on a P4 2.8GHz dual core.
