PRO-300, Windows 11, WiFi. Until last week, Professional Print & Layout would accept drag & drop of JPGs and print just fine. Now it shows the checkerboard pattern after the drag. File->Open behaves the same way. I upgraded to Windows 11 several weeks ago, but it worked after the upgrade. This is v1.3.0.
