Bio-degradable 3DMF

Well, maybe not.

We have found that successive saving and opening of 3DMF
files containing deeply nested groups gradually lose their
contents. First a polygon will lose its attribute set, then on the
next save/open cycle the polygon will disappear, then another
polygon will lose its attribute set and turn white, then it will
disappear too.

Has anyone else seen this problem? It is possible it may have
been fixed since my branch of Quesa diverged from the main
trunk, but I don't remember seeing any e-mails about anything
similar.

I see exactly the same problem using drag and drop between
applications, using memory resident file objects.

Any ideas?

Roger.
