'Update Expansion List' shows 'X kb of Y' where Y is an unfeasibly large number (in I don't know what units), or perhaps just a number with very many decimals. I can't quite tell, because the number flashes up and is gone. Shift-F8 didn't seem to get a screenshot, and a screenrecorder that I have - which has a limited F.P.S. - did not capture it. But perhaps someone here can capture or freeze the output.
