I'm having the same type of issue. It seems to pop up when there is a unity issue like when I have the auto-hide turned on for the Nav bar and I try to switch desktops or when I tried to move a Chrome tab out of the current window into its own window.
My mouse buttons are not usable until I log out and back on. When I tried moving the Chrome tab, the window followed my mouse like the button was still depressed and no combination of keyboard or mouse buttons were able to break the 'stuckness'. When I tried to switch desktops I got stuck seeing 4 desktops with content on each one but I was not able to click into a desktop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993655 Title: Unity looses mouse click handler when using enabling USB headset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/993655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
