QC restores int vect during shell?

[neil at ac.dal.ca]

     Using MS Quick-C 2.0, I am trying to debug a program that 
uses an interrupt driver. The compiler has routines to read the
existing vectors and install the new vectors. I occasionally find 
the need to shell out to debug to examine certain chucks of the 
box. My "problem" is that QC seems to retore the old interrupt 
vector value when the shell is loaded. The new vector is again 
reloaded after the shell has returned. This seems like a nice 
touch on QC's part but is infuriating for this application.

     Does anyone know if what I am seeing is correct?
