@Benson Shaw thanks Benson, yes, a reboot did clear the issue. However, that issue immediately followed there prior reboot, so—I don't understand. What I do understand is that it took a bit of careful looking to understand there was a problem (see Mr Stanford's reply above). I thought for a bit my clicking was off, or there was another problem I couldn't parse or…etc.
Did I try all the selection tools available in the toolset? yes. Windows were tabbed. The machine, brand spanking new. Specs attached. VWX 2019, SP Latest.
And of course all that time, not a stitch of work got done, blood pressure rose, on and on and on. Rant? yes.
Over for the moment.
