No, I didn't, but I can give it a quick whirl. I think I still have one or 
two machines with 6.14.x DDX that I can put in UMS mode and see what 
happens.

Haven't used UMS for at least 2-3 years. My bet is that it is more likely 
that I will hit a few unrelated UMS problems that are there even without 
my patches, but I'll let you know the result when I have it.
