I object to the implication that using the startup script exactly the way it's designed will break something! And the commands I suggested work without accessing the RF console.
The OP stated that his tilde key doesn't open the RF console. And AFAIK, there's no way to enable the legacy menu without the command console or using the startup script. The commands I suggested will force that message off and the legacy menu bar on every time RF starts - whether his tilde key works or not. And if he gets his tilde key working, those commands in the console still toggle them.
I have no idea why his tilde key shouldn't work - he obviously has one and used it in his post. I'm not aware of anything other than the tilde key that will open RF's console. So I suggested a way that works without the console.
