** Summary changed:

- Logout "save?" dialog inaccessible - window list frozen; Not obvious when 
logout is stalled by window on another virtual desktop
+ Not obvious when logout is stalled by window on another virtual desktop / 
window beneath front-most one / window is minimised

** Description changed:

  Description of the problem:
  It is possible for certain programs to stall the logout process so they can 
ask questions. If such the program that does it is on another desktop, the only 
way to see that desktop is by using keybord shortcuts (plus it is not obvious 
that you have to check the other desktop).
  
  Steps to reproduce:
  1. Make sure no gedit windows are open on any desktop.
  2. Press ctrl-alt-right to switch to another desktop.
  3. Go to Applications -> Accessories -> Text Editor.
  4. When gedit appears type 'a' so the document becomes unsaved.
  5. Press ctrl-alt-left to switch to original desktop.
  6. Go to System -> Log Out <user>...
  7. Click on Log Out.
  
  Expected result:
- Desktop to be switched to desktop containg dialog stopping the  logout. 
gnome-panels to remain responsive until the last possible minute.
+ Desktop to be switched to desktop containing dialog stopping the logout. 
gnome-panels to remain responsive until the last possible minute.
  
  Actual results:
  Desktop remains on desktop not showing the logout stopping dialog. 
gnome-panel applets become unresponsive (Window List and Workspace Switcher no 
longer respond to mouse input). No indication of which desktop needs attention, 
only way to see the dialog is to use ctrl-alt-right .
  
  Mildly related to Bug #4406 .
  
- Edit:
- Bringing another window in front of gedit is enough to cause trouble.
- gedit flashes in the taskbar, but you can't bring it to the front because the 
window list is frozen.
- In fact, *all* gnome panels are frozen.
+ Additional information:
+ A variant of this  also occurs when the gedit window is underneath another 
window and is completely covered or gedit is minimised. gedit flashes in the 
taskbar (so it is obvious that something needs to be done), but you can't bring 
it to the front because the window list is frozen (it is not obvious how to 
provide the required attention). In such cases the user may be forced to 
alt-tab to gedit in order to bring it to the front.
