I sometimes use an extended monitor on my laptop. somehow in the process of packing up, hibernating, sleeping, whatever I did, I lost the default tray on the second monitor. No amount of restarting sketchup, turning on/off trays, minimizing, maximizing, or other windows level “consolidation” tricks that I could find would get me the default tray back. I had to plug in another monitor and find the default tray and return it to the main display. Its 2021 and I’m running sketchup 2020. We should be beyond this kind of silliness for a product we pay good money for.
