I have compatibility problem using mootools mega menu with mootools slideshow.

mootools menu: http://www.aplusdesign.com.au/blog/m...enu-drop-down/
mootools slideshow: http://davidwalsh.name/mootools-slideshow

Theses are about the only 2 out of many dropdowns and slideshows that I could find that didn't conflict with anything else on my joomla site, hence why i am using mootools for everything.

Basically the problem is... user hovers over main menu item and the dropdown menu drops down infront of the slideshow, all is ok, all is normal..... whilst the mouse cursor is on the dropdown menu it should stay visible as it does, until your mouse goes onto the area where the slideshow is behind. As soon as the mouse touches this area (the mouse is still on the dropdown menu, but the slideshow is behind) the dropdown will disapear.
Please see link below, you will see what I mean.

Any help/pointers or anything would be much appreciated!
Thanks in advance!
