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.
Symptoms: You have a runny nose that just won't stop running. If it lasts more than 6 weeks, you might have a case of pregnancy rhinitis. Cause: An increase in hormones can cause the inside of your nose to swell and the mucus there to thicken. These two things together can cause you to feel the constant urge to sniff. If your nose constantly drips, you can thank hormones again.
