I might try this; it may or may not happen today, but at some point in
the near future, I will make a duplicate copy of my program, undo the
'workarounds', and start chopping away at it, to try to minimize the
size of the program that still exhibits the unwanted behavior. If
successful, I will send a reply to the list with my findings, and
depending on the size of the remaining source code, just send it out
(list if only a few K, otherwise to Frank's private address).
