I have been using the 'dCAD Calculator' DA for a long time. I recently
got a larger monitor (Sigma Designs L*View) and now find that the
DA is 'broken'.

Symptoms:   Selecting the DA under the Apple Menu drops me into MacsBug,
almost always with a 'Bus Error' in the DA handler.  Rebooting is
the only way out that works. The calculator window shows briefly on the
primary screen (whichever it is) before the crash.

System: Mac IIci with RGB 13" display on internal video (primary screen, has
menubar - although making the other monitor the primary doesn't fix this),
8M, 80M internal disk, L*View monitor in left slot.  Running 6.0.7 (the
DA worked on this before the new monitor).  Removing all non-Apple
code from the System and System folder (except the init that drives the
new monitor) does not fix the problem.

Any suggestions on how to fix this would be welcomed. I'm pretty
resigned to this being fatal to the DA, so suggestions on a good
calculator DA would also be welcomed.

Thanks.
