Sometimes, not always, I get into a period where the Layout page palett focus is not being released when I click bask onto the page. I can try to edit a text, entering “3” in the text field. That will not produce the written number 3, but instead a travel to page 3. :-).
On a Mac, most recent release of OS and sketchup.
If I minimize the pages palette and open it again, it works until next time i click in the pages panel.
