I reported it to both companies, since I do use VersaTerm and Mathemetica
together a lot. The following is a partial list of my log:

--10/20/89:
Problem: Under Multi-finder, launch VersaTerm-Pro, Quit, launch
Mathematica, Quit. System bombs, sometimes with ID=11, ID=10, or simply
freezes in middle of window updates. Call to Wolfram Research: --bug in
Apple Palette Manager,try system 6.0.4 and call back
--10/23/89:
Follow-up: Installed 6.0.4. Problem still occurs. Increased Finder memory
allocation. Problem no longer reproducible, but still occurs. Problem also
occurs running VersaTerm and Telnet without Mathematica.
[Hindsight 5/10/91, this went away after next upgrade of Telnet.]
--11/15/89:
Call to Synergy Software:  Lonny Abelbeck: Bug in initialization of other
programs (e.g. Mathematica, Telnet). VersaTerm-PRO has history of exposing
bugs in other programs that way (a case was a beta copy of Adobe
Illustrator). Possible workaround: turn off "shared" attribute of VT-PRO
using ResEdit & "Get Info". Follow-up: "shared" bit already off.
--17-apr-90:
Received 3.1.1 upgrade with communications toolbox. Operating under system
6.0.5 with multifinder 6.1b9. Mathematica bombs upon launch after launching
Versaterm, even when started using serial tool instead of native serial
link.
--31-may-90:
Found readnews article on complex interaction bug between AddressBook,
VersaTerm, and SuperClock under MultiFinder involving modem port. Author
claimed problem was modem port usage coupled with an application calling
"InitWindow" before "InitFont". Suggested using hex edit tool to find "A9
12 A8 FE" and changing it to "A8 FE A9 12". Found and changed two
occurances in Mathematica. Result bombed in presence of VersaTerm. (Also
found "A9 12" in CODE resource "Main" ID=1, did not change it.)
--18-jul-90:
Found readnews article which stated that Multifinder had  "A9 12 A8 FE" bug
as well. Found one occurance in CODE resource "INIT" ID=1, as well as one
occurance of correct "A8 FE A9 12". Rehacked Mathematica and Multifinder
(6.1b9). Did not find occurances in VersaTerm-PRO or Darkness 1.01.
--19-oct-90:
Updated system version to 6.0.7.
--22-oct-90:
Talked to Tech Support about current status. About a month ago, Synergy
Software (Versaterm) contacted them about a bug in VersaTerm causing
problems. Current version of Mathematica is 1.2.2.
--13-nov-90
Received upgrade to Mathematica 1.2.2, and MacTCP 1.0.1. First trial
suggests that Versaterm and Mathematica can now run simultaneously.

--10-may-91
I am currently running successfully with Multifinder, system 6.0.7,
Mathematica 1.2.2, and Versaterm-Pro 3.1.1 (both with and without CTB).
Evidence seems to support Adelbeck's suggestion, that Versaterm leaves
memory in such a way that certain bugs in other programs are exposed.
