floats before section

[Bob Lounsbury]

I have the following command in my preamble so that floats are not 
placed before a there corresponding section. However, the code does not 
work for the Appendix sections.

\let\mySection\section\renewcommand{\section}{\suppressfloats[t]\mySection}
Is there some other command I need to use or add so that floats are not 
above the appendix section titles?

Thanks,
Bob Lounsbury
