Same problem here. An old HP mouse (could not figure out the type) sends mostly multiple buttonrelease events. I have connected an additional Logitech M570 (restarted nothing, just plugged in), and that one does the same. Watching their behaviour in xev it seems that after connecting, the m570 is much more prone to erroneous behaviour. Actually it seemed that the "first" mouse behaves badly. This machine is very old and not upgraded for a long time. I see that the last comment is 3 years old to this bug. Maybe it is silently fixed already?

For example: - Click on a window title bar to focus the window occasionally causes it to maximize - Click on a document in nautilus to select it occasionally opens the document - Clicking on toolbar buttons in any app occasionally causes the button action to occur twice On an updated fresh install of 10.4 beta 1 (xorg 1:7.5+3ubuntu1), with home directory preserved from a previous install of 9.10, where this problem did not occur. The log from xev of this problem looks like this (from a single click): ButtonPress event, serial 33, synthetic NO, window 0x4c00001, root 0x15d, subw 0x0, time 14769063, (80,82), root:(1819,659), state 0x0, button 1, same_screen YES ButtonRelease event, serial 33, synthetic NO, window 0x4c00001, root 0x15d, subw 0x0, time 14769159, (80,82), root:(1819,659), state 0x100, button 1, same_screen YES ButtonPress event, serial 33, synthetic NO, window 0x4c00001, root 0x15d, subw 0x0, time 14769167, (80,82), root:(1819,659), state 0x0, button 1, same_screen YES ButtonRelease event, serial 33, synthetic NO, window 0x4c00001, root 0x15d, subw 0x0, time 14769175, (80,82), root:(1819,659), state 0x100, button 1, same_screen YES --- Architecture: amd64 DistroRelease: Ubuntu 10.04 DkmsStatus: nvidia-current, 195.36.15, 2.6.32-17-generic, x86_64: installed virtualbox-ose, 3.1.4, 2.6.32-17-generic, x86_64: installed virtualbox-ose, 3.1.4, 2.6.32-16-generic, x86_64: installed InstallationMedia: Ubuntu 10.04 "Lucid Lynx" - Beta amd64 (20100318) MachineType: Gigabyte Technology Co., Ltd.
