When you say "to restore proper control" to what extent was full control not returned by closing-and-restarting BBC BASIC? That should have re-initialised everything.

No, that's not going to help you - it's specifically to get you back to the menu after deliberately entering immediate mode. But it won't have that effect on a crash or an accidental exit to immediate mode.
Before you go any further I would experiment with repeatedly closing and re-opening BBC BASIC. That should be absolutely fine, just as it should be with all other apps, and any 'loss of control' requiring a reboot indicates that something is seriously wrong.
