Please can someone at Zemax stop Universal Plots doing an unnecessary recalculation when you switch between the Graph tab and the Text tab.  Universal Plots are used for carrying out multiple calculations and some of mine take a long time to generate.  Zemax shouldn’t need to do a recalculation to show you the values it used to generate the graph when you select the Text tab, after all nothing has changed.  It is just a waste of my time waiting 15 minutes or more just to access the data values.
