Martin,

         Thanks much for your recognition that this topic has now strayed far, far away from NVDA.  Presuming you are using Windows 10, you could ask on the Windows 10 for Screen Reader Users group:

• Post: win10@win10.groups.io
• Subscribe: win10+subscribe@win10.groups.io
• Unsubscribe: win10+unsubscribe@win10.groups.io
• Group Owner: win10+owner@win10.groups.io
• Help: win10+help@win10.groups.io

Even if it's not Windows 10, what you're seeking advice on predates Windows 10 itself, but is still pertinent there.
