(Webb) It is a hard reboot or maybe a momentary power off, it is hard to tell
which. (It does a full memory test)

(Webb) All of the above: PROCOMM, VDE, INSTACALC, SPELL, and at the $ prompt,
there does not seem to be any pattern.

Brian:

After cleaning the battery contacts with an eraser, I have not had a reset.

I did spend about an hour this morning going round and round in the NEC voicemail system looking for a replacement switch because I thought that might be the problem and did not want to disassemmble my beloved Ultralite without a spare switch. PARTS does not list the switch and TECH SUPPORT could not tell which Suba$$embly held the switch.

Thanks Webb
