I often get this message that does not allow me to undo (F3). I tied closing Zemax and re-opening it to see if it disappears but it does not.

 

I checked to see if such a file exists, and it does not exist. So I am not sure how to proceed. Please advice.

Hi,

I've encountered something similar. It may be a (server) setting that does not support saving intermediate steps to disk

 

Best regards

Server setting ? I am using Zemax on my local PC though.
