Any possibility of getting this resolved soon? I believe that we are very close.

If we have time, I would like to see what Ed gets with the most recent fix. If we absolutely need to release today, then I will push patches 2,5,6 which are covering Ed's particular situation. My concern with doing so is that other failures might pop up. Thanx, Paul
