Yes my flor 1.1 does the same thing on short journeys. However,if you use 'initially' the air con this will dry the air (more) in the cabin and help prevent this. Also it's very good for demisting the screen at the start of any journey as the air is drier. Don't forget that body heat and moisture ( sweat/breath) vapour will condense onto a cold surface, as heat migrates to a colder surface such as window glass after you've parked the car.
Whilst driving, a good idea is to crack open the front/ rear windows a little to allow the moist air to flow out and have the fan on #2 or greater with air coming in from the outside. Recirculated air doesn't help unless you are stuck in smelly fumes.
Without causing offence, try to breath in and out through the nose, If you use your mouth it will exhale more moisture into the cabin which will later condense on the windscreen. This is a useful tip I've found to keep passengers quiet.
Hope this helps?
