Topic: lens distorsion
just downloaded the latest version. if i go to "lens distortion correction" a window pops up to fill in the values. if i do so and confirm or press "preview" nothing happens. the computer is busy for some seconds, but the image doesn't change, whatever value i fill in. if i press o.k. i can undo the lens distortion, but as nothing happens, the image still stays the same.
i'm using windows xp. what could this be?
thanks in advance
