On the whole defMON is a fairly stable program, but there are a bunch of glitches here and there. If you find reproducible bugs yourself, don't hesitate to let me know. The preferred way to report a bug is to make a post about it in the defMON thread at chipmusic.org.
Please make sure that you are using the latest version of defMON before reporting a bug!
