I'll try to keep a better eye out for when it arises. One or more of us is not expression him/herself clearly -- I say this because I am now quite confused. To use the example of kmin, the functional forms of most of the window functions are such that they go to zero at kmin-dk/2. It's always been this way. The exception is the sine window, but it doesn't go to zero at kmin, either. I suppose that I might be missing the point entirely, so I'll leave it with this: without a convincing screen shot demonstrating the problem, I am going to assume that there isn't one.
