Thanks a lot! It works now 4 days before I'm handing in, you saved my day!

Here is an example of my problem:

\documentclass[final,a4paper,11pt,fleqn,dvipsnames,article,twoside,openright,english]{memoir}

\usepackage{amsmath}
\usepackage{subfig}
\usepackage{graphicx}
\usepackage{todonotes}

\setsecnumdepth{subsection}
\maxtocdepth{subsection}
\numberwithin{figure ...

I know that chapters are unnumbered in frontmatter :)
The problem is that my figures in mainmatter lose their chapter numbers when I start my document using frommatter:

\frontmatter
abstract etc.

\mainmatter
main document (no chapter numbers)

If I deactive frontmatter I can see the chapter ...

I am writing my master thesis using the memoir package.

I use \frontmatter for table of contents, abstract and so on, and \mainmatter for the thesis.
I use
\makeatletter
\renewcommand\@memmain@floats{%
\counterwithin{figure}{chapter}
\counterwithin{table}{chapter}
}
\makeatother
and it works ...
