                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 1st half user reported the guider (TUI 1.1) would not guide on a star
with the DISslit viewer correctly.  Kept moving another object that it
though it should be guiding (actually a bright galaxy). At least that was
what appeared to be happening with TUI 1.1.  On my TUI (1.2b5) things
looked fine and it stayed locked on to the star.  My guess is that is has
to do with the changes between 1.1 and 1.2 and I wouldn't call it a bug,
but is confusing for the 1.1 user. It did indeed show the guiding cross on
the galaxy in TUI 1.1 which I confirmed with my laptop running 1.1.
