Using flash for your site menus should be prevented because they lessen the chances of your site to be crawled by search engines. Why?
Search Engine crawlers use the links on your page to crawl your other pages. For example, your index.php contains a flash button that is linked to a forum.php. Since the link is encoded within flash, then there is no way that web crawlers would actually recognize it. But, if you placed an <a href="forum.php"> instead of the flash button, then the web crawler will be able to crawl to your other links.
I myself have been using flash menus and I just recognized the risk that I was doing. If you want to know some of your site's problems and errors, try google sitemaps, it'll be a good help.
