Yes, we are frequently to be found on water patrol in the mornings, drying up windows with shower wiper, mictofibre cloth and/or windows. We usually leave the windows open on a catch during the day to air the place, have installed as much insulation as possible and improved the heating (from electric to wood pellet). We don't actually have mould anywhere but the bathroom - where we now have an extractor fan - but that's no reason not to play it safe!
There's only so much you can do to most houses, and the rest you just deal with
(hmm.. if we ever go away during the winter, I think those windows will be on the catch and towels left under each window to catch whatever condensation runs down... luuuuurvely...)
