To be honest, we don't know for sure.  Without knowing exactly how the man=
y instances have been created in your case, it is hard to answer.  If you =
had been invoking ConfigureAndWatch multiple times, then yes, this is like=
ly fixed now.

BTW, 1.2.11 has been released something like 20 months ago, so you may wan=
t to give it a try.
