STB corruption of View

Christopher J. Demers
See my previous message: "STB corruption on View test in ViewComposer..."
posted on 01/16/2001 for more information.

The problem has now damaged a view such that it can not be opened in the
ViewComposer.  It seems to be a somewhat random  problem.  The class name,
in this case IdentityDictionary has become corrupt in the STB Collection.  I
had been making changes in the ViewComposer and saved the view.  Everything
worked the first few times.  But then the last time I saved it the view
generated a walkback when I tried to show it that demonstrated this
corruption.  When I tried to open it in the ViewComposer I got the same
walkback.

This is the beginning of the byte array.  If you examine this as a string
you can see where the beginning of the IdentityDictionary class name has
been corrupted.  I can send the entire byte array if it is needed.

This looks like it could be a fairly serious problem.  I am going to move to
another image incase something is bad in the image.   However I would like
to try to understand this problem better.  I would like to know what's
happening, and why.
