Question: Interior Windshield Steams Up

When the car is idling the interior windshield steams up, temp gauge is in the middle. This happened a couple of times. Than tonight the windshield steamed up while driving in traffic and eventually stalled with the temp gauge in red zone.
Car has 72,000 miles, I just bought it used, just had anti freeze topped up two days ago with BMW specified added to existing non BMW anti freeze. Windshield steamed up before I did this.
