I cannot explain this answer either and I have a degree...it gave me a whopping headache...I was thinking about going to DC, but if this is the answer that I get I will just stay at the bar at the airport... Stefan...remember we are doctors, not computer linguists...we probably just got yelled at by some little old lady who didnt get her MEDCO rx on time..so take it easy on us please...if I come to DC I will buy you a drink...many drinks...so we can explain some of these little nuances to my scientific and yet very cynical brain....thanks for listening...todd
