I have a problem using the standard Spectrum visualisation.
If I use more than 40 bands, the bottom part of the Spectrum display "drops down" below the window edge and I cannot see the frequency marks anymore. Is that a bug or user error?
There is not enough room in your display to show all of those frequencies.
For 80 bands, on my screen the spectrum must be about 1240 pixels wide to show all the numbers.
You can make your display larger, or double-click the spectrum display to view it full-screen.
Double-click again or press Esc to return from full-screen...
I see now what happens at 80 columns if I change the size of the Foobar window, the numbbers are running into each other. But it is still weird that they don't shift on to rows (staggered). They "dissapear".
PS: Maximizing the window shows just the center of those columns. 1600x1050.
