Comment 2 for bug 162790

I have the same problem but:
- I have it in all programs I tried where there is a context-menu: OpenOffice.org, gedit, gnome terminal, nautilus
- it often also causes a clipboard paste, as if I clicked the scroll-button (I take care not to accidentally click; I never have this while scrolling down)
- I have this problem from time to time; not sure what makes it go away or reappear: rebooting? updates? an update to which package then?
- I'm not sure but I think I also experienced it in PCLinuxOS

by the way: it's very annoying!
