Out, damned log window

I see the log window all the time. NB I mean the log window, not the activity window. And yes, I have checked the box offering me the option not to see it. But it still appears. The activity window appears and then disappears. The log window just stays there until I close it. I’ve searched this forum for answers and found nothing. I don’t think apple M-ing it constantly counts as a good solution.

Under what circumstances? What’s it reporting?

It stopped doing it, so I couldn’t answer you, but has started again. There is nothing wrong with any of the files it claims have no text.

“Missing File” errors are always immediately reported as that’s a serious issue (usually caused by third-party software or the user removing/renaming the file in the Finder).
