To further clarify my remark in #23, when this happens when I am using a USB mouse, if I right-click using the touchpad, all is back to normal. It does not matter if I unplug the USB mouse or not.
I was assuming that unplugging the external mouse was making it work again, but that is not the case. It seems that using my touchpad mouse instead seems to shock the system back into working properly.
