Hi Paul,

Just returned from a DOS boot, and this is exactly what happens, right down
to the last keystroke (normal config, with Autostart macro):

1. MSGED [CR] ... Autostarted to the Arealist.
2. Arrow down ... Highlighted PUBLIC_DOMAIN area.
3. Press [CR] ... Opened lastread message.
3. Press L & R arrow keys to navigate ... Immediate QEMM Exception 13.

Rebooted (hard reset) and tried again with no Autostart macro this time:

1. MSGED [CR] ... Interesting info screen which I've never seen before.
2. Press [CR] ... Entered netmail area (first listed in squish.cfg)
3. Press Alt-A ... Open Arealist (all areas indicate UNSCANNED).
4. Press [*] ... Arealist now shows all messages as expected.
5. Arrow down ... Highlighted Z3_OS2 area.
6. Press [CR] ... Opened lastread message.
7. Press L & R arrows keys to navigate ... Immediate QEMM Exception 13.

The QEMM message says to press (T) to terminate the app, or (R) to reboot. 
Neither key works, nor does C-A-D.  Had to hit the Reset button each time.

The ONLY variation on the above is that a couple of times, I had to press
and hold the arrow key to scan through the messages (as in step 7 above),
and after a couple of seconds, it still locked up solid.  This is not just
an occasional thing, it happens EVERY time without fail.

Dunno if it helps at all, but until such time as the *.SQD message base
file has been opened by Msged, everything worked just fine (not that
there's all that much to do without opening your message base for read
anyway).

Regards, Bill
