Spring RTS Engine

In SpringLobby, how do I specify (drawing or command) the start boxes for "Choose In-Game" setting?

All I could find was:
viewtopic.php?f=1&t=13261&hilit=choose+ ... tart+boxes
Which simply states: "draw boxes on the picture of the map", which unfortunately is not working. I also tried using the "shift" key, as described for TASClient, again to no effect.

(Ubuntu Linux 14.04, if that matters)

If it's in an (spads) autohost, you can use this:

Crap, forgot to specify that - no, it's not in a SPADS autohost, it's in a regular Battleroom lobby.

I want to make a few experiments as single-player with AIs, to see what I can do regarding them choosing their starting position.

Do not use the small minimap that you see on right side of playerlist.
At top go to the "map" tab, there will be a big map and there you can draw startboxes with mouse.
You have to use developtest version because it is bugged in latest released version (0.243) https://github.com/springlobby/springlobby/issues/603

That did the trick, I can now create starting boxes. Thanks.

(now if only I could stop procrastinating by spectating Spring matches)
