Vertical space not respected in the pdflatex output

[Paul Smith]

Dear All,

When I insert a vertical space in the beginning of a page, such a
vertical space does not appear in the pdflatex output. (Please, see
the attached file.) Any ideas? I am using

$ rpm -q lyx
lyx-1.5.6-2.fc9.i386
$

on Fedora 9 (Linux).

Thanks in advance,

Paul
