Hi, I had this problem in the past with the menu disappearing behind flash banners and was able to resolve it with your help using <param name="wmode" value="transparent"/> but this doesn't work with the Microsoft Weather Widget I am using - see www.aboutcampello.com/pages/information/weather.html.
I have looked at the dmxNavigationMenu.css and tried to use z order to position the menu on top, but as yet had no luck!
Thanks in anticipation of your reply

Please add: wmode="transparent" to the <embed...> that is located in widgetbox_widget_div_0. This should fix the problem.

Thanks for your reply, but the only code to embned the widget is this

<script type="text/javascript" src="http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js"></script>
                  <script type="text/javascript">if (WIDGETBOX) WIDGETBOX.renderWidget('976560f0-9140-4cdf-8ac0-03c7f31c9c4d');</script>

Sorry, i was inspecting the widget source code.
Unfortunately this is the only way that this can be resolved. You can try contacting the widget support and ask them how to change its wmode.

Thanks again for your help. I did get the widget source code and was able to get the desired result from adding code to that, so for this time the problem is resolved, however, I thought that if I could use the z-order to make sure the menu is always on top, then it would save me similar problems in the future. As I previously said, I have tried using z-order in the css to force it to the top but this has not worked. Anyway, thanks again and I am grateful for any advice and guidance.

Happy to hear it is all ok now.
Just for clarification - The problem is not with the z-indexes, it is the way flash renders on your page.
