Condensation on Double Glazing

We recently had 3 large patio doors installed and have found that in the mornings we have heavy condensation on the OUTSIDE of the glass, which gradually disperses as the morning goes on. Why is this and should we complain? We have had double glazing throughout our house for over 20 years and never come across this before.[/i]
