I am using Dreamweaver 8 and creating images with Illustrator CS 2.

When you mouseover the service titles around the circle on this page --
[url]http://www.vaxainc.com/newsitewip/content.asp?catid=116[/url] -- the image is
swapped to reveal a brief explanation of the service.

The problem is --> when the swap takes place - the image appears to move a
slight amount. I use Illustrator to create these images and ensure the same
clipping mask is used each time and it is in the same place. I dont have this
problem on the following page --
[url]http://www.vaxainc.com/newsitewip/content.asp?catid=16[/url] -- when you mouse over
FRONT END EXPERTISE or the other header buttons for the table - a smooth swap
takes place.

Any suggestions as to how to not have images move when you do an image swap is
greatly appreciated.
