Also having trouble: Please help!
I'm also having some trouble with show-hide layers. I am creating a drop-down menu for my site and have been successful except for one thing. After adding in the behaviours (show and hide on mouseover) to the menu headings and going on the browser, when i mouseover the headings i put the behaviours on, the drop down part works but when i go to click on the object that drops down - it dissappears

this may have been hard to follow but if you under stand...what am i doing wrong? If you don't fully understand, paste the html on to your dreamweaver. Please help me!
