  I was working quite happily in WIM last week and playing about with the Task Board, using the check boxes on the Task Board menu to show and hide various panels when 'all of a sudden' (i.e. I don't remember exactly what happened, but I wasn't trying to do anything clever or devious, just using the app and the menus) I lost all the optional panes in the application and now get a popup error message titled "An Exception Has Occurred" with the text "DocumentPane must be put under a DockingManager!".  Uninstalling and reinstalling don't resolve this issue.  I've now got an app with a ribbon menu and nothing else.  Any ideas?

  I found the answer... after uninstalling, I deleted the "Work Item Manager" folder from my documents and re-installed.

  Hi Ian,
  
  It looks like there was an issue with the saved state of the dockable panes in the app (i.e. area/iteration pane, queries pane, etc.).  Whenever you close the app, the layout of the panes is saved to your user settings file (UserSettings.xml), which is in the folder that you deleted.  Upon startup, the app tries to restore your previous layout.
  
  If you experience this problem again could you post the contents of the <PanelLayout> node to the forum?  That would be very helpful in debugging this issue as we have not seen it before.  Also, if it happens again, try going to the "View" tab in the ribbon and checking some of the boxes in the Panes group to see if you get the panes back.  If that doesn't work, instead of deleting the entire folder, you could just delete the <PanelLayout> node in the user settings file.
  
  Thanks,
  
  JP

  Same problem, but UserSettings.xml doesn't exist. :(
  
  Any update on this problem?

  Hi Francois,
  
  We have not made any recent code changes to address this issue as we were never able to reproduce it.  In your case, since you say you don't even have a UserSettings.xml file, I would've expected the app to work fine because if the file isn't there it should behave just like a brand new WIM install and use the default layout for the panels.
  
  Has WIM ever worked for you or did this problem suddenly appear?  Can you provide some more details about the steps that lead to this errors?  Also, can you check the WIM log file for any errors?  The log file is located here: {My Documents}\Work Item Manager 2010\WIM-log.txt.
  
  Thanks,
  Joel
