It looks like you're new here. If you want to get involved, click one of these buttons!
I'm getting a weird thing were Sending a message in a conversation greys out the send message button and puts the wait symbol next to it, even though the message is sent. This can be fixed with a simple refresh.
The next oddity is the "Leave conversation" button. If you just click it, it waits forever. However opening it in a new tab or copying and pasting the link leads to the "do you want to leave?" dialog, allowing to leave as you would expect.
Anyone else know if this is a bug in this version? Or is there something I am missing?
