I'm playing Ticket to Ride, Europe, online using the Steam version on a Macintosh. I understand the rules of stations, just not how to physically place on the game board. For example:

In this map I'm attempting a route from Madrid to Wien. My opponent has blocked me from Müchen to Wien. You can see in the lower right hand corner that I have 3 stations available. If I click on my stations I get the same dialog that I get if I click my avatar, the one that shows routes complete, train cards, route cards, and trains. Curiously, it does not list stations. I've tried all the modifiers, control, command, option, shift click etc...

I cannot drag to the made route, I cannot click on the cities where I want the stations. How do I place a station in the online version?
