ASI received UWS 2.2 on Thursday, February 1.  UWS 2.2 contains Ultrix
3.1 and window system version 2.2.

Some notes:
	- Follow the upgrade instructions carefully. It is necessary
	  delete all of the UDW(RISC) or UWS (VAX) subsets prior to
	  installing UWS 2.2.

	- The X11 subset has become unsupported under 2.2 and is now 
	  called UDWUNMIT022.  The binaries for this subset have been
	  moved from /usr/bin to /usr/bin/X11.

	- The /usr/lib/X11/system.uwmrc file seems to have some
	  problems which will keep /usr/bin/X11/uwm from starting
	  properly.

Question:
	Has anyone out there experienced problems with shared memory,
	specificially with virtual page corruption.  Under ultrix
	RISC, release 2.0, there were major problems.  Under 2.1, we 
	experienced similar problems and they apparently exist under
	2.2 as well.  We have been unable to nail down the problem to
	a specific example, but the same programs execute flawlessly
	under all current VAX ultrix releases.
