When you ask for a periodogram, by

it has no sense the selection of a bandwith here, because the values of
the periodogram must not be weighted, and in fact they aren't. Gretl
presents the crude periodogram values and they don't depend on the
bandwidth you put in the box.
You're right -- at some point the two menu items under the
/Variable/Spectrum menu seem to have become confused (presumably
as a side effect of some other change). The "Sample periodogram"
item should not have a window-size selector. That should be fixed
soon.
