I discussed this bug on the forum (​https://winswitch.org/forum/topic/10/) and I've finally managed to get a screenshot of first bug I mentioned.

Sometimes the menu's don't expand to anything. Example: I see the local server, I click on Start Applications and the menu is empty (I just see a sliver showing something should be there, it's just not populated with anything.) However, this happens with ALL the menu options for all attached winswitch servers/connections. When this happens I can't quit the applet. However, from another system I can start applications from my that system.

See attached screenshot.

I'm using a MAC client 0.12.8 and Ubuntu server (0.8.12.1-1 & 0.0.7.33-1). Applications don't start at all, but Desktops do.

Server log files attached.

This is an upstream ​Twisted bug, I have created a ticket there: ​ticket 5496

Not much we can do at this end, as it just looks to us like the key is invalid... Maybe we ought to show an alert message in this case?
See also: #190, since MS Windows does not have support for pageant, we need a way to load the keys ourselves!

Also somewhat reminiscent of #160
