Al,
if it's any help, my Firefox did an automatic update a day ago.
Once before when it did that, replying to any IIS threads was all
buggered just like you described.
I think it was either the FF update messed up the Flasplayer addon
or vice versa.
Within a day or so another update came thru and it fixed itself.
