I am having a pesky issue while putting together my cross functional flow charts that I would like to prevent.  When I accidentally click and drag a swimlane, it moves.  Is there a way to change a flowchart property where it will not allow a user to drag and drop columns?  We have multiple people editing the same flowchart and sometimes people accidentally mess it up by dragging and dropping a swimlane instead of the boxes inside the swimlane.  

Thank you for your help!  I can't seem to find a setting anywhere that disables drag and drop of swimlanes.

First, ensure you have the Developer tab enabled. Now select a swimlane, then Developer -> Protection

and check X Position and Y Position.
