	Yes, 3.10b (and 3.9 as well), which again runs under VMS, does
not have this problem.

However there is some confusion, under VMS, concerning the new method
MicroEMACS uses for "safe" saving.... ie EMACS opens up a temporary
file, writes the buffer out, kills the old version, then renames the
temp file to the old name.  This makes saving very "safe" on other
systems, but only succeeds in confusing VMS's version system.  So under
VMS in MicroEMACS version 3.10 and above add this line to your emacs.rc
file:

	set $ssave FALSE
