in the documents list. Applies to MindManager used with Mindjet Connect.
If you don't want anyone else to make changes to a document you can
lock it. Other members can still view the document but they cannot edit
it, and they will see that you have the document locked
in the documents list.
You can lock a map either before or after you open it. If you lock a map while other members are editing it, you'll see a warning, and if you proceed with the lock they will no longer be able to make changes to the map.
Members who view locked maps will see the lock information in the Map Status indicator in the upper-left of the Map View.
To show or hide the Map Status indicator, on the MindManager View tab, in the Meetings group, click Map Status.
Files (non-map documents) are automatically locked when they are checked out for editing, and unlocked when they are checked in, but you can also manually lock and unlock them.
Members with Reader access for the workspace cannot lock documents.
Do one of the following:
Select the document in the Documents list, then on the Workspaces tab, in the Document Access group, click Lock.
Right-click the document name in the Documents list then click Lock.
The "Locked by me" 
icon in the Documents list indicates documents
that you have locked. You will also see this icon in the Map Status indicator
if you edit the map.
Unlock the document by following the same steps, but click Unlock.
Workspace Owners
can break locks on documents locked or checked out 
by other members:
Select the document in the Documents list, then on the Workspaces tab, in the Document Access group, click Break Lock.
If the document was checked out, the checkout is discarded. Any changes made to the document that were not previously checked in are lost.
If you leave a workspace or if you are removed from the workspace by another member all your locks are removed.
