If I click No, it returns me to the Ethernet Properties sheet with the multiplexor protocol disabled. If I click Yes, it unchecks the multiplexor protocol and then closes the dialog and property sheet. The googler wasn't very helpful, here.
Uses. Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/ cold sores, gingivitis).
There are several grades of hydrogen peroxide. Not all are safe for home use. Swallowing small amounts of household (3%) hydrogen peroxide usually is not dangerous. It can create a lot of foam, though. Household hydrogen peroxide can be irritating to eyes and skin. Higher concentrations can cause burns.
