I can't myself see any change in the slider positions in that case
(using the latest highpass.ny) but Nyqust generator plug-ins do seem
(at the moment) to consistently produce the wrong length when the
plug-in interface is used. 1 second at 44100 Hz only gives you 43968 
samples and 2 seconds gives you 88255 samples. But many of us 
have seen examples in earlier Beta versions where the length generation 
is incorrect by various factors which vary from machine to machine.
