That is interesting.  The formula I use, and the one that Global uses has never 
shown any sign of that in my experience, and I hasve never heard any reports 
that it has (until now, maybe?)

This formula is very widely used by commercial and hobby beekeepers, so any 
such reports would be of great interest to all.
