But the real time scans look normal.

I exited and tried Restart. **PSPT PROBLEM**: Sun Sep 26 19:40:19 GMT 1999 Restart didn't work, tried Run, still waiting for a response. Something has changed in the programs, I can see the Obs menu for exiting and other options scroll by on the screen when I try Restart, but it doesn't need to and won't stop to let us enter an option anyway. The first Run didn't work, it didn't get past the "taking three exposures" point, I stopped it before it does its normal thing of trying 128 times and giving up. Then I tried Run again. **PSPT PROBLEM**: Sun Sep 26 19:53:52 GMT 1999 OK, that last Run seems to have worked, it is pointing again, just in time for a new batch of orographic clouds. If it runs into guiding problems again I'll have to try to close down for the day until I can find more time to look into that problem. PSPT COMMENT: Sun Sep 26 19:56:10 GMT 1999 On the good news side, I haven't noticed any unfocused images since Randy's software changes involving giving the telescope more time to lock on the sun before taking images, so hopefully that problem has been reduced or eliminated.

I opened the cover and there wasn't any sun on the beam splitter or either mirror, which makes sense. I manually pointed to the sun and the program eventually started displaying images of the sun.
