I am running off the USB that has 3.0.3. I always, out of habit, set up my workspaces to a 4x1 layout. That is sufficient for my needs while in a temporary worksession.
BUT when I click on a different workspace, guess what: the popup pager appears for an instant BUT WITH A 4X3 desktop layout instead of the 4x1 configuration that I just did. I guess I can ignore it, but it is puzzling to say the least
