Hi,
When you edit and save a process in Lookout, the previous .lks file is overwritten by the editor, and therefore, any comments that you have added will be overwritten as well. There isn't a method to retain those comments from one version of the process to the next.
In general, National Instruments does not recommend that you make changes to the .lks file directly unless it is absolutely necessary.
Regards,
P.J.
