Bug in Cinnamon 2.4 on Linux Mint 17.1; window controls not working

[freemangilgamesh]

Occasionally window controls are no loger working and it seems like the windows is frozen! This bug happened to me many time on my HP and Dell laptops (Both i3 with 4GB of RAM).

I've had this happen as well. Someone else reported this in IRC. For me going in and out of expo mode fixes the problem.

go back to 17.0 or somone will fix it?

Same problem here. Sometimes if I right-click an application in the panel and select minimize it fixes it. Not sure what info to provide.

Same issue here; loss of control except for everything in the task bar. If I right click and close one of my apps from the task bar, full control is regained. Happens with Qiana, Petra and Rebecca which I am currently using. I'm using a dual monitor set-up on a Dell Optiplex 790 workstation.

WORKAROUND: I was able to Ctrl-Alt-F1 into a terminal (which looked like it was in 40-column mode!) and then Ctrl-Alt-F8 back into Cinnamon and the window manager started responding again fine.
