<(CM) Support tip> HPRM and CM9 auto checkin

In HPRM and CM9 there is an open documents prompt that is displayed when a user has checked out a document , closed the authoring application,  but is yet to check it back in  (It's the old auto checkin function)

This can be turned off individually by the end user (via the open documents "options" screen) or on by creating the following reg key and setting to value to 0.
