Is anyone else having trouble with the server lobby not showing up? I do not see anything in the chat pane except a solid light grey. If I try to create a game I get the error that you cannot create a game in the main lobby and then everything shows up. Is anyone else having this issue and is there something I can do to prevent it?

I'm not seeing this on my PC, and I wasn't seeing this on my previous version, though that was 5.3.x and I hadn't used it in a while...

Hmmm... looks like if you pull the bottom outer boundary down far enough everything will show up, but the default is too short. Better than creating a game...

I was going to point that out. When it creates the windows for everything, for some reason it doesn't create the lobby to the right size so it doesn't pop into existence until you try to create a game (believing yourself to not be in the lobby when you are).

Mac users will have to get used to slightly different quirks when using Vassal.
