Yes, MEDM is one of the main culprits for us.  The enum drop-down menus
become stale, which is pretty bad in this case since the menu continues
to display the old string list, but MEDM sends the underlying int, which
in turn maps to a new value on the server.  We've had many occasions
where the operator has sent bad requests back to the server because of
this.
