White lines between buttons on pages

I used webGFX, I get small white lines between the buttons on some pages.....Please visit:
This web site

If you have any clues as to what would make this white line problem go way please advise.

i don't see any white lines

nice looking nav bar...

I looked at your site using IE and there were no white lines. What browser did you see them in (let me guess - NS?)

Sometimes you can get gaps between the images because of funny table formatting. Try putting the whole nav in a separate table inside one cell, rather than in different cells.

When programs like FireWorks slice an image into a table of smaller images, you always get a line of shim images which set the height / width for each row / column, pulling all the cells together. If you still get the white lines, try re-slicing the image in something like FireWorks then importing the table it gives you.

White lines? what white lines?
I am using Internet Explorer 5.50 I see a thin white line below the "Home" button on the php page.
But if no one else can see it I think I'm wasting me life with it.
Thankyou to everyone.

You just asked this question to get people to your site didn't you?
