Thank you!!!  I'm glad we didn't have to find that out the hard way...  Our
stack is not yet 8,000 cards but will be when all of the data is in.  I have
just one followup question:  To spare us the nuisance of having to convert all
of our machines to running 6.0.4, can we do most of the development under 1.2.2
still?  In other words, when does the corruption occur:  If it is only a
problem when adding cards then we can make sure to do all card adding under
HyperCard 1.2.5 and other sorts of development (changing scripts, etc.) under
1.2.2.  Or would this still be opening ourselves up for trouble?
