You asked,
...The main VI is basically a state machine waiting for user clicks to go to one of the sub VIs, which e.g. displays a xy chart of measurements... How can I get the main VI to commence working (not waiting for the chart window to complete and return)?
Michael responded,
You will have to use VI Server to do this...
While Michael's approach will work and is probably preferable, I think you might also accomplish the same thing by putting each of your selectable subVIs in its own loop parallel to the state machine loop. Use the state machine to enable the execution of the appropriate subVI for one iteration of the subVI's loop. One loop being held up until its subVI closes will not interfere with any other loop, including the master state machine's.
