X-Midas Users Take Note:
Unlike X-Midas, there is no global message queue in NeXtMidas. There isn't even an option to use a global message queue (so don't ask). Each command has its own message queue that is automatically created when the command is run. Consequently there is no need to manually turn on and off the message queue--unlike in X-Midas, all of the messaging is automatic... and there is no global message queue.
