This bug was introduced in versions 5.14 and 5.15 and it has been fixed
recently in the CVS. Unfortunately, replacing plotdf.lisp by a new
version will not help, because the bug was in plotdf.tcl. In Windows,
that means you need to build a new Startkit for xmaxima, and I do not
currently have a Windows system to do that.
For the record, the source of the bug was some options added to
plot2d.tcl. I forgot that plotdf(...[xfun...]) invokes plot2d.tcl and
should also be modified to reflect the new options.
