In MecaStack this is displayed in the output.
That message is displayed 100% of the time, it's static. A few months ago we made it where you can have the output window open and still modify your input parameters at the same time. We added that static warning just so the user realized that even though they may have changed the input file, the output results were not updated until an analysis is performed. Sorry for the confusion, we couldn't easily add the capability to have the output window dynamically add that warning only after there was a change to the input file.
