Hey, unfortunately, there is no option to hide that bar from 2X RDP Client. But we will forward this to our development team as a feature request.
Hello, I can't see the picture that alwaysbeme92 inserted but i'm wondering if the question was to close this bar and if it was if there is any development?
That client version looks antiquated. Please try to use the latest Parallels RAS client as that bar was overhauled quite a number of versions ago.
