A last question, when this last loss of mouse button events happened, where you doing/ had you just been doing something particular? Was there a background process that kicked in? Were the open applications the same every time this happened? You can find a lot of information in your log files (in Gnome you can use the System->Administration->System Log tool to help you with this). Note the time of occurrence and what you were doing and then check the log files to see if anything interesting is reported just before and after the event. We must find a way to correlate this to something: if this is random it is going to be VERY difficult to hunt it down. -- loss of mouse buttons https://launchpad.net/bugs/92092 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
