I had brought up Print/Export in a floating window. While Print/Export was up Logos had recognized a new resource I purchased was available to be downloaded so it put up the message to allow me to download them. I believe I clicked to dismiss the Print/Explort panel and then clicked to download the new resources (but I might have done those in the reverse order). In any event, I did them in quite close proximity. My screen was left with this glitch, until I forced it to repaint:

Log file attached (note that it later crashed for unrelated reasons and that's being reported as a separate bug): 3487.PaintGlitch.zip
Note: the crash I mentioned parenthetically (and which shows up at the end of the log file) is the same old "Holy Spirit' "Biblical People" crash which is a known problem, so I won't report it again. But it's unrelated to this repaint problem.
