If the MIDAS Setup command is invoked to edit the ODB database the variable /Runinfo/Transition in process is set to the value 1. The run status changes to CHANGING.
The run state may then not be changed before the variable /Runinfo/Transition in process is reset to zero! As a consequence, no run may be started until the respective command in progress is correctly terminated typing exit or quit.

If you are absolutely sure that the run state is stuck to CHANGING, you may reset the variable /Runinfo/Transition in process to 0 following one the possibilities shown below:

go in the MIDAS Setup tab. If the run status is still on CHANGING a button Reset Changing will be active. By pressing it the status of the run will be reset.
