MusicBee not looking for album art

[aabeba]

In past versions, MusicBee always, without fail, at least attempted to get album artwork for a particular album when I right-clicked on a track or album and selected 'Search Internet for Picture'.

Now, I've been adding albums to MusicBee one by one and, every now and then, MusicBee will simply refuse to look for art. I can tell because the prompt appears instantly. I'll add one album, find art, save it, great; add another, repeat, works fine. Then, I'll add a third album--no less obscure--and MusicBee won't even attempt to trawl the web for art.



Changing the title of the album to something simpler makes no difference.

Re-adding the album to MusicBee makes no difference.

Again, this never occurred with the versions I used before I installed a fresh copy of MusicBee a couple of months ago. I just updated to the latest version and it did not seem to help.
