Bug Description
Good morning
Please accept my apologies for not selecting a package where my bug is because I am not sure. I will apreciate it if you could assign it to the relevant place.
have looked through all the 'Alt+Tab' bugs reports and none of them seem to quite relate to my situation. Bug reports 971051 and 993187 seem to be the closest. I have a number of user accounts with admin rights. One I log into Gnome Classic, one into KDE and one into Cinnamon.
Since I did an update two weeks ago my whole PC freezes after I have pressed Alt+tab a few times (usually on the fourth time). All the open programs windows become about 80% transparent. I then have to switch my PC off and then back on again. It started sometime after Firefox was upgraded to version 21.0. I originally thought that it was Firefox causing the problem. I have subsequently found that the problem occurs without Firefox being open. It happens when I have more than one program window open e.g. Nautilus, Audacious, LibreOffice calc, terminal. I have compiz installed. I am also experiencing the same issue in my Cinnamon session. I also noticed that the 'Window List' applet disappeared off the bottom panel.
I checked 'keyboard settings > shortcuts > navigation' as per one of the suggestions and Alt+Tab is there. I checked Compiz manager and the Window Switchers are enabled.
I do not know if this is a factor. My Huawei E220 HDSPA 3G modem does not work with the 12.04 modem manager
