Recently, I've had a very disturbing bug in a program I'm writing.
In this program, I'm receiving IDCMP messages from two seperate
windows (depending upon which the user selects, obviously). I setup
a waitmask by using the mp_SigBit from one window's userport, and
logically or'ing it with the other window's mp_SigBit. Everything
works just swell, but every once in a blue moon the system crashes
with a "Unknown IDCMP message" guru (8400000D.00000000). Yes, I am
checking for NULL messages. 

Has anyone else experienced this guru? It's quite baffling,
actually, since it would seem to suggest it's not my fault. I can
post a bit of source if someone thinks it would help, but its in
assembly. Thanks in advance.
