How about Display Character Set on the Options Screen?

What happens if you compile with slang library (Kanji support OFF)?
(What does the Kanji support of slang give you, by the way?)
I do not find your shifting effect on that page with slang on sol
(SLANG_VERSION 9937, I assume that means Kanji support is off).

It would at least make it more easy to tell us what form fields you are
talking about, as in "Number [16]".

You don't say what size your screen (or window) is.  What is "under" e.g. the
11th option line may be totally different for different screen sizes.

When I pretend to have a "Japanese (EUC)" display character set (of
course I don't), there is no problem with shiftings of that kind.

Anyway, does your problem really have anything to do with whether what
its under the popup box are other form fields?  Or is that just
accidental, and it depends on what characters are on that line (either
in the popup box, or the rest of the line)?
