Thanks for letting me know. I am still using MP 1.12, and have only just downloaded MP1.16 pre-release for testing!I can confirm that the info button is working OK on the release version of MP 1.15
In the forthcoming version, the INFO button is controlled by the XML file, and not by the AHK file, so it may well behave differently on your MADVR system.
