The error does not go away when I request to go back to WINDY or reload the code. I am unable to go back to observing while it persists. I have left a message on Jim's cell phone and am looking at the code.

02:56 UTC Fixed, back to observing.

I found the relevant code in /opt/rtcds/userapps/release/isi/h1/guardian/sei_config/manager.py. I ran an svn diff on it and found uncommitted changes that looked like they could be causing the problem. I copied manager.py to manager.py.backup and ran svn revert on manager.py. I then reloaded the code from the guardian screen. The error went away and I was able to go back to observing.
