So I tried installing both Cakewalk and the new Free Sonar on a relatively new surface pro. Nothing but hang-ups or freezes.
I was sure it must be a "Cakewalk" issue. Yesterday, I tried to install Cakewalk (not the new Sonar) on a Lenovo Ideapad (I5, Windows 10). Installation - NO PROBLEM!
Something to do with Microsoft product - don't know what, but disappointed.
