buttons in nav bar not working properly

[charliescoffee]

I’m building a web site using Web Designer. The site has a vertical nav bar that I essentially pulled down from the button gallery with a few changes. First I had a links tab of the web properties window, I’d get xara.com. This problem may be getting fixed, at least now some of the buttons are working correctly. However, now, in a browser, when I move the cursor across the buttons, they group together and all (the first four, actually) point to the address for the first button. If I move the cursor into the button from below it, it works properly. Any ideas? The site is at: MasterPrintmakers.org
