I haven't seen anyone report this so it may be just my computer. I'm running 4.51.0.2040. When I open a note in a floating window, I move it to my second monitor. When I click back on the main L4 window on the primary laptop screen, the panels will not change focus. Scrolling still works but I'm not able to select another panel.
If I float another window other than notes, such as a Bible or commentary, I can change select other panels. I have tried multiple notes with the same issue. The other panels can be selected as long as I don't float a notes window.
Log file is attached.
