Whenever I get a Steam Notification pop up it stops me clicking anything on the panel at all in Cinnamon 1.8.
I think it's problem from Cinnamon side. I've got same problem using Kadu after upgrading Cinnamon from 1.6 to 1.8
Possible dupe of #663
Closing as I can not reproduce this issue with Cinnamon 3.0.
Nothing extracted yet.
