Hi Richard,
The site is working now and is...

I managed to find a fix to my problem. I didn't explain it well in my message.
I used PNG files for my menu links and took away the border, colour, hover colour, etc. settings so everything was see through but when I put my mouse over the drop downs a box appeared with 'False' written inside. I couldnt see the txt at first as the box was very small but I did another test with bigger buttons and then I noticed this.
You were helping another user who in turn found a fix which was to change the 'visibility' to 'hidden' on the ul.MenuBarHorizontal iframe rule. This seemed to fix my problem too.
I saw what you said to her about her SpryMenuBar.css and SpryMenuBarHorizontal.css being corrupt and to replce them. I had already tried this by using your newer SpryMenuBar.css code as I was using an older version but this didn't work for me.
Anyway my problem is fixed, it probably isn't the correct way to do it but it's working so thank you for your reply.
Thanks again.
