Please do include this combined use.
I'm having troubles with overlays in softwares like MS-Office when the blank screen is on.
The overlays don't show anymore until I turn off the blank screen.
Other than that everything is working fine.
We are going to re-write the blank screen feature anyway, so this ability will most likely be included.
I think Capture Alpha Blending should be a stardard setting auto enabled.
We'll certainly consider making this a default setting. Meanwhile, you can simply enable it in Tools -> Default Connection properties and from then on all new connections that you create in the Viewer will have this option selected.
