but same machine, same program wont run in operator mode. it'll qualify probes, but click the start button and the program pauses right away... crickets... no dialog boxes, no run box, nothing...
also, the program will run in both operator mode and online mode on other machines (we have 5 here).
Was there any changes to the program before you created the Marked Set? Try creating a new Marked Set, and make sure there's no GOTO statements in the marked set that may be skipping features.
