limoric - I know exactly what it is...Once one of you gars are attacked by this dreaded disease unless you take immediate and unhesitant action you will loose your entire humidor. There is only one cure, you have to ship the entire contents of your humi(s) to someone overseas within a 3 day period. Plus, you have to mail them on the third Saturday of the month. Oh, I just noticed that would be this Saturday and since I live overseas I will volunteer to help you with this terrible burden. =)
Never had this happen to me before. Sorry, can't help you =)
Regards,
B
