I wrote a small patch to make special enemies such as bees work today.
Keep in mind that I am a total C newbie, and I have only had the chance to test this on the shareware episode. So this might not work as well as you might expect. Although it seems to work pretty well on my computer.

You can find a zip file with the patches and a compiled OpenJazz.exe with the changes over here.

[New version that improves it a bit, not perfect though because it doesn't clean out the behaviors when the playing loop is ended.]
