Our website is created entirely with Coffee Cup. Mind you, several of us work on different pages and none of us our web designers so we have to keep it pretty basic. We just received a call from one person who says when he opens our web page it is completely distorted and the text is bigger. As far as I know, he is the only one with this problem. I've had several people check from different computers at their homes and no one else has this problem.

Our website is www.newtongov.org

They look the same size to me in Firefox & IE7. Sounds more like that particular person tweaked their text size in their browser.

I noticed something else though. I don't see the dhtml menu in Firefox 3.
The source code says VSD 5.3. There's been a lot of changes since, including improving the sites looking consistent between browsers. Also, make sure you have the latest DHTML Menu Builder:

I know I've seen many forum topics on getting the DHTML Menu working well with Firefox, so be sure to search a little. I lack the experience with that department. Here's a couple threads, if they might help:

The DHTML menu you used is not up to date. The version available at the link Adam provided may allow the menu to be visible in Firefox 2 and 3.

Be sure to let us know how things work with the menu.
