Carbon Copy (software) Carbon Copy was an early remote control and file transfer software for DOS and Windows published by Microcom. It allowed remote access to a computer via dial-up modem connection.
A viral infection (the common cold) is the most common cause of a stuffy and/or runny nose, but allergies, influenza, and sinus infections also may cause these symptoms. Less commonly, anatomical obstructions (e.g. a deviated nasal septum, foreign bodies) may lead to nasal congestion.
Post Nasal Drip:Post nasal drip occurs when an excessive amount of mucus accumulation in the nose and throat creates phlegm and causes coughing. Phlegm seems to build up in the throat overnight, which leads to congestion in the morning.
