Mona,
I note that jmg has been disabled as a contributor to this forum. I surmise that his recent "malicious bug" diatribe was a rant too far for some sensitive soul or other at PTC.
However, in spite of the occasional misguided bee in his bonnet and the often less than tactful way he expresses his views, jmg has contributed a lot, both to the old collaboratory and the current forum, helping many Mathcad users, old and new.
It's a weak Company that can't take criticism, even if that criticism is unjustified (especially if it is unjustified!).
I suggest you re-enable jmg.
Alan
