Works for me.

This is from src/window.c:

Split WINDOW, putting SIZE lines in the first of the pair.
WINDOW defaults to the selected one and SIZE to half its size.
If optional third arg HORFLAG is non-nil, split side by side and put
SIZE columns in the first of the pair. The newly created window is
returned.

I would try to ask on the xemacs-beta mailing list for help under which
circumstances this can happen.
