Thanks, Dan, for the notes.

this was related to pausing the 'hal expose' macro - it was paused very =
early (before BOSS or APOGEE actually started), but when it was resumed =
apparently the APOGEE shutter wasn't opened. If it becomes evident that =
there's a bug in the pre-exposure checks of the 'hal expose' macro when =
it's paused/resumed (which isn't common), then we can file a ticket, but =
for now I'm treating this as a one-off.
Did you pause the =E2=80=9CHal expose=E2=80=9D or the software did =

Jose and John:  Can you please investigate why cherno is unable to =

until the issue is resolved?
Thanks,
