[Chimera-users] savepos/reset problem with sessions and volumes

The problem is that Chimera does not preserve the model numbers of
volume data sets when it restores a session. Restoring a saved position
then moves the wrong models because it remembers the position associated
with each model number. There are two Chimera bugs here. First the
volume data restored from a session file should use the original model
numbers. And secondly, even if the model numbers were to change, the
savepos information should be updated to use the new model numbers.
These problems exist in all versions of Chimera on all platforms. I'll
work on fixing them and send you email if I get it working. I think I
can fix the code so that your existing session files will restore
correctly using the original model numbers.
