Observing Summary:

Clouds and cirrus all night.  Difficult guiding due to clouds.

Everything was fine until 11:30 UTC, while we were trying to 
move the disperser, prospero gave us the same error as a 
previous night (10/4).  We tried to reset the disperser, but
it did not come back.  We solved the problem following the
same procedure as last time:  cycled power on IE, then restarted
all of the data acquisition software.  Run ossetup in prospero
as Rick suggested, and everything went back to normal.

While trying to slew to zenith at the end of the night, the
equinox set-up stopped responding, and then the xtcs panel 
vanished.  We reopened it, and reset the link from MDMTCS.
