Window noises

[nsk040]

With windows all the way up, I hear some creaks at low speeds going over bumps. Turning into a driveway that has a slight ramp up/down would be a good example of something that would produce the noise. I don't get these noises when the windows are down, so I'm thinking it's just the glass rubbing against the seals. Has anyone else experienced this / or does anyone have a solution?

Thanks
