DW rollover behaviour shifts centred table to the right

[elephantchicken]

OK, I have put together a quick website which has centered tables on every page. All of the pages on the site appear exectly in the same place when I switch between them, but if I place a rollover behavour onto an image it alters the page so that the centred table shifts slightly to the right.

The only way I seem to be able to get around this is to create an iframe and load the html with the rollover into it.

Any ideas what coulds be causing this?

Thanks

But a SWAG would be that your rollover image is a different size than the image it is replacing.
