I would say it's more of a design choice than a design flaw.

When you put the top up if you raised the windows all the way the car has to move the windows down an inch again.

Personally I think it would be nice if the windows would automatically go down when I lower the top. It's not very often that I have the windows up with the top down.

Besides the windows are fully automatic, it's not like you're straining to push two buttons at the same time once.
