Shiu wroteI've tried pretty much everything I can think of on my mac and had four friends also test it. But we can't reproduce it. Only way for us to fix it is probably if one of you who have the problem can share your computer (while you're at it of course) with Team Viewer and we can then try and see if we can figure out what is causing it that way.
@shiu I don't mind. I am on the IRC channel, same username. We can schedule a time for team viewer.
Note: I just update to the latest 1.9.15, with the same problem happening
