v2.2
-fixed cookie bug

v2.1
-Mouse events states for title bar
-object index bug fixes
-redesigned to look like XP :)

v 2.0
-W3C HTML 4.01 Transitional compliant
-Support for initially open menu
-New fading capability
-Cookie menu persistence
-Redesigned code


Notes:

If you want a menu to be open initially set the style display to
"inline" in the subMenu class div like this...
<div class="subMenu" style="display:inline;">


The fading effect can be disabled by setting the 
doFading var to false. I have only tested this feature on 
ie 6, Netscape 1.7, firefox 1 & 1.5

If the user has cookies enabled the script will bake a cookie ;) on
the browser to track the state of the menus. This is good news for those
of you who don't use frames, you can now have persistent menu states

Make sure you put the java script include tag after all the menus otherwise
it will not be able find and initialize them. If you have questions, or comments
about the XpStyle Menu v2 send me an email.

And lastly a plug for myself, If you need some professional help with technical
web development please drop me an email, I do contracts for a competitive price. :)
