Ok so I think I've found a bug. Hopefully someone else can try or confirm before I report it.
Go to Label Legend Manager. Pick a fixture, go into "edit fields", turn on "Purpose." Now from there I've gotten a few different crashes. Some times it crashes as soon as you click "OK." Other times I got back in to the manager and it crashed when I clicked on "edit layout." If I use the default fixture it crashes hard and instant. If I try on a fixture I added it seems to freeze and never recover. I haven't tired all the options and it seems to happen on some of them, but not others.
