Tag Editor error -- window resizing

When you are no longer able to resize the Tag Editor window to work with Trados Workbench do this:
1. Go to Start > Run
2. Type "regedit"
3. Go to keyname HKEY_CURRENT_USER\Software\Trados\TagEditor\Settings
4. Right click on this key and choose Export. Please choose a location to temporarily save a backup of this entry. Your Desktop is fine.
5. Delete the "Top", "Bottom", "Left" and "Right" entries from the right hand window.
6. Close the Registry Editor.

Please reopen TagEditor and you should now be able to maximise and minimise the TagEditor window. If this has worked successfully then feel free to delete the registry key backup which you made earlier.
