Dear all

I have quite a large program which uses a set of library files to decode 
images etc.  I recently removed one common function which I used to update
the user (me) if the system was doing something, a very pretty little turny
roundy type of thing, called ScreenUpdate().  I thought I had removed all 
references, and had certainly removed to source code, but due to my rather
lapse version management some still crept through.  The files containing 
the spurious references compiled fine (ScreenUpdate() was declared as
external) and also linked without any complaint.  Upon executing the code
it obviously jumped to some weird address and proceeded to s**t all over the
screen.  Only when it displayed a general protection error and the 
accompanying stack dump did I get any idea of the source of the problem.

Is this a known bug or what?

Lots of Love
