I have an MX-980 and an MX-1200 working with an MSC-400 (I've got both remotes in my showroom system so I can compare the two). On the MX-980 I've programmed the MENU button in each activity with a Press & Hold macro. Tap the button for the Menu IR, Press & Hold >=2seconds for a jump to a SYSTEM SETTINGS page. This has always worked perfectly on the 980 but on the 1200 it just locks up the remote. It stops sending any commands and I have to remove the battery. I've even tried reversing the IF/ELSE command to be Press & Hold <1second for the Menu IR, ELSE Jump to SYSTEM SETTINGS page. Same result. I don't get it.
