Disappearing Menus

Is there an auto-hide preference for the menus at the top of Cubase 7 - I keep getting a weird thing where all menus at the top disappear - occasionally I can get them back if I put my mouse cursor in the right spot, but often it appears the programme has become unresponsive - no indication that it’s saving when I press Command+S, although actually I think it does save.
NB this is on a project started around 4 years ago on an earlier version of Cubase (can’t remember which)

You’re using Mac OSX Snow Leopard 10.6.8?

Not supported…i know, it sucks since Mountain Lion is junk.

Ah Goddam! Thanks, I failed to spot the OS 10.7 min requirement…hmm that leaves me in a quandary
