Our work around was to have a couple of very strong rubber bands linked together so however far you have the window opened we could get a nice tight, but not too tight, hold of the door against the window - it doesn't bother us at all - its a simple fix and one we are happy to do as a tradeoff for having large windows on both sides of the door - plenty of light inside and great in Qld in the heat. We bought a box of the strong rubber bands from office works, cost under $5 so no problem if one breaks or perishes after use. Works well for us.
