No, it's totally independent of any CHS action on my part - at least it seems so, but then, my taskbar is hidden so it might be happening when I do something, and I only notice it later. I thought it might be due to a periodic automatic clipboard reconnection, but that's not turned on. Also, it actually takes two left-clicks to make the icon disappear. I use CHS 2.19.01, and it's still happening.
