Recording desktop video of Cubase with Camtasia - menus left

Hello everybody,

I have special question - I run blog and made desktop videos with Camtasia 8 in Cubase 8.5. When I start recording, all dropdown menus from Cubase is gone. (I mean File, Edit, Project …) When I stop Camtasia - all is back.

I tryed Movavi screen capture soft and problem is same.

In Cubase 5 it was no problem, everything works properly.

So have somebody experience with this behavior?

My system is laptop HP Elite book 8470p - Win 7.

Thank for help
