When loading an MB app compiled with version 5.5 on a version 4 MI, the app starts loading then MI crashes with a system error 33012. If I use my own 4.12, I got the message that MI cannot load the MB app because of version compatibility. Would that same message appear with a plain version 4.0, or 4.1? I know there were many changes between 4 and 4.12, what the MB version trap one of them?
