I've seen this before together with a technical explanation that I can
no longer remember. I would guess you are running the application from
a batch file in which case you may be able to cure the problem by
inserting the line:

set comspec=%comspec%

immediately before the line in your batch file which runs the
application.

This certainly worked on my PC when it happened to me.
