I am getting a lot of crashes when I use Ubuntu 12.04 lately. When I browse my folders to open something, the window crashes, and all the icons on my desktop disappear. I can open it again, sometimes it is ok, other times it crashes again immediately. At some stage the desktop icons reappear. I always get a window, 'Ubuntu has experienced an internal error'. I tell it to report it. This has been going on for at least 3 weeks now.
I always have the latest updates. Is there anything else I can do?
