Subject: Another strange one...

Dear all
We seem to have a bit of a problem with cormas on one of the computers.
After installation (and checked - image is working) we save the image, and
reopen it, and we try to import the model, we get the error of "Warning -
defined with nil superclass". On inspection, it seems that class GroupComm
no longer exists. Trying this with the other models gives the same type of
errors - seemingly Cormas classes has just disappeared from the image.
The only way to solve the problem was not simply reinstalling cormas, but
downlading the Kernel and Messages of cormas 2001, copying it to the
directory, replacing the old folders, and then reinstalling cormas. I don't
understand what went wrong in the first place, it is as if the original
Kernel and Messages - files have actually been altered as well. Anyway.
Problems solved. Checked the image is working, saved and closed it, open it
again and try to import the model, and there it is again: "Warning - defined
with nil superclass", and GroupComm is, again, missing in action.
If anyone had this problem before, and knows what to do about it, please let
me know.
Thanks
