I'm not even sure how to reproduce it because now I see the boards almost instantly and going to 'options' and hitting 'apply', seems to work normally now.
Yesterday, I noticed I only get
'TypeError: layoutdocument has no properties' if the boards aren't loaded, and when I go to options>menu and hitting apply would result in a pop-up of that error.
But now it seems fine, since I now see a list of the boards in 'options>menu'.
