Hi Michael,

How are you extracting the data with your macro? Is it through a Numeric Function like GETT or GETL? Or is it through the keyword GETTEXTFILE? I think this pop-up is probably appearing because the POP window is open on your screen. If you use GETTEXTFILE, then you will be able to extract the POP window data without needing to open the Physical Optics Propagation tool at all. That should allow you to avoid the pop-up message.

Here is an example of what I mean:

In this image, you can see that the only windows I have open are the macro and the Text Viewer output. I am still able to extract the data and print it to the Text Viewer. I can also choose to simply save the data without re-printing it with something like this:

You can use this in conjunction with MODIFYSETTINGS to update the POP settings and save the new output. Without MODIFYSETTINGS, the output will match the settings last saved to the CFG file. Could that work for you instead?

Let me know if you are still seeing this pop-up even without opening the POP analysis. 

Best,

Allie
