Button distortion 2

This is a great site!
I am creating a website for a photographer and the text he wants to use is not a flash compatable text. So I created the text navigation in photoshop and imported the images into flash as gif files.
When I convert these gifs(bitmaps) into buttons they look distorted. I read a post about tracing the image and about breaking apart the image. The tracing makes the image look bad (because it is text) and break apart doesn’t help. I also made sure to place the images on whole numbers on the stage.
Is there anything else that I can do to fix this problem? Why does this happen?

One wierd thing is that if I place the non-button (bitmap) version of the image on the stage, along with the symbol sometimes it fixes the problem. But, I figured someone here would know the correct way to fix this problem.
