@Aaron, my workaround is to kill nm-applet (not Metwork Manager itself) and restart it. It does fix the issue for me... for a few hours, until it appears again (but that also applies to logging out and in).
It's annoying though because the only way I know of doing this is from a terminal, and then I am obliged to keep the terminal open forever (even though I relaunch nm-applet with "nm-applet &" with the "&"). But I guess someone can give us a solution for this? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1019395 Title: At random times NM applet menu stops responding Status in “network-manager-applet” package in Ubuntu: Confirmed Bug description: At random times, Network Manager's whole menu stops working. If I'm already connected (I mainly use wifi), then network keeps working fine, however none of the items in the menu does anything. Examples, I click on Edit Networks => nothing happens. I click on Disconnect => nothing happens I click on more networks => a tiny empty submenu is shown (instead of a list of available wifi networks, and there are plenty of them here) Rebooting fixes the issue. This is almost certainly a regression in a recent update, as I never experienced this until recently. This may be happening after suspend/resume, but I'm not sure.
