Cab Sealed... Too good?

[RobUSxyFk]

So I’m having what may be a good delima.

I’ve got an 85 C10 that has one little flaw and it’s driving me crazy.

When I have the windows up, the cab is so well sealed that the doors are hell to close due to the pressure.

When the windows are down, the doors close like a charm. But people accidentally “slam” the door (seemingly with the force of a thousand suns) when the windows are down, because they’re used to the cab pressure keeping them from easily closing the door.

Is this just... normal?

Thanks! (First post here, by the way. Glad to be here!)
