Web pages show left justified, only some pages orig centered why?

[Andy.Tait]

I have a lot of Visio drawing published to web pages.
But there are a few pages that have been created and in Viso they look
centered.
But when you publish it, it will be left justified in the HTML other pages
in the same document are entered?

I am thinking it is a setting that has carried over from it's original
creation. But I can not find the setting? Create a new page and it will be
centered. Cut and paste the information of the left justified page and it
will be come Left justified.
