prevent float placement on page with /newpage

[Csikos Bela]

Hello lyx users:

I have a question on float placement.
I am working on a document with sections, and I start every section
on a new page inserting an Insert>Formatting>New page
before the section title. But lyx occasionally places floats on the
same (new) page above the new section title.
How can I prevent this so that the section would start
on a completely new page and the float would be inserted
on a previous page?

Thanks,
