Muhammad-I am using a Mac G3, System 9.2, and Explorer 5.0 Mac edition. The JD ad on my system lays there quietly until the mouse passes over it (usually on the way to something else) Once the dropdown occurs, I can't get rid of it. I can change between the four tabs, but one of them stays down all the time, until I go to a new page. Once the dropdown has occured, any of your page links that might get covered by the dropdown, go dead until I refresh the page or move to a new page. This is really irritating, but at least I have found a work around.BTW, you have one of the best web presentations I have ever seen. I really like your discussion software, many sites are so poorly presented that I have quit using them. Just a thought, you might want to put a link to the user control panel some where on the home page.Keep up the excellant work, you are obviously performing a valuable service for everyone.
