Click outside of Nuendo Screen and recording stops

This is a very odd one and something I’ve not noticed before. I’m running Nuendo 6.05 on a Mac Pro, under 10.9.2 with two screens. Nuendo works well, but if I click anywhere outside a Nuendo window whilst recording, Nuendo drops out of record mode and stops. When I reactivate the window by clicking inside it, It automatically starts back up in play mode.

Can anyone else confirm this, or is it something peculiar to my system?

Thanks,

John

I wonder if you have “Release Driver When application is in Background” activated in Device Setup>VST Audio System?

That would be it, thanks. No idea how that came to be checked, but then I’ve been away from the studio for a while. I suspect a student…

Much appreciated.

John
