** Description changed:

  Binary package hint: xorg
  
- At times the mouse stops responding to clicks, or will only be able to
- click on things in one application. I can still move the mouse, and the
- keyboard still seems to work as normal. This is following an online
- update from Lucid to Maverick beta.
+ Following an online update from Kubuntu Lucid to Maverick beta, use of
+ almost any of the 'special' buttons on the keyboard (mail, home,
+ documents, play/pause, volume up, zoom in...) fires a ButtonPress event
+ (as seen by xev) for the physically left mouse button (i.e. left click
+ with the mouse set right-handed, 'right click' if set left-handed).
+ There is no corresponding ButtonRelease, so the computer acts as if that
+ mouse button is held down. The ButtonPress occurs between the KeyPress
+ and KeyRelease events of the special key.
  
- One way that seems to reliably trigger this is to use the keyboard
- 'mail' button: a right click menu appears where the mouse currently is,
- then the input breaks. (The mail button launches Thunderbird)
+ This makes the mouse essentially unusable. So far, I've not found a way
+ to reset it besides logging off (i.e. restarting X).
  
  Hardware:
  - Basic Microsoft keyboard and mouse (optical wheel mouse, Digital Media Keyboard 3000)
  - Intel graphics (lspci says it's an 82G33/31 integrated graphics controller)
  
  Initially I thought the problem was related to kwin compositing (which
  also causes some problems, see bug 630632 ), but I've found it happening
  even with desktop effects turned off.
  
  I don't know if xorg is the best package to file this against, so if
  not, please point me in the right direction.
