Thanks Greg! Hope you've gotten my message by now regarding running as root. the placement of the file confirms my theory; you have a local installation instead of the system-wide installation. Haven't really looked closely at the file from dosemu.org since i let debian install dosemu for me, but i think there is a way to do system-wide installation. If you had a system-wide installation, your conf file would be in /etc or /etc/dosemu. Sorry if you thought i hadn't addressed this question but I did so, either in the message where I requested this file or in the next one. You need a _sytem-wide_ installation to run as root. Hope this puts you on the right track. Thank you for the file. Hmm, haven't tried running megadots as root. Given that mine is a sytem-wide installation, maybe that would work, but I'd really rather run it as user.
