I remembered a thread from several years ago and dug it up. Maybe some help...

Try using the search feature on the top task bar, searching for your code or "IMRC" or "runner control".

There is some info there, just nothing recent as the IMRC setup has not been used for several years now.

Hope you get is squared away.
