Edit in Wavelab Pro 10 fail

If I send a clip to WL and add a process and then return (update) it to Cubase, Cubase looses it’s connection to the ASIO driver. The only way to get it back is to close the Project and reopen it. In WL I have clicked on “Release driver when Wavelab Pro is in Background”.

Is it possible that this feature was not checked out before releasing C11?
