It's 4:30 in the morning here, but the answer came to me in my sleep <g>...
Which just shows how dense I've been the last couple days.
In PR28 I allowed the busy class to be set as a template setting, and changed the default class for the graphic from bdiv to nt-busy. I removed the bdiv class from the shipping styles.
Of course for static pages, hard-coded with the graphic and style, this matters. In the pages example, index.htm for example, there's a line
<div id="_busy" class="bdiv"><img src="images/_busy.gif"></img></div>
and this either needs to become
<div id="_busy" class="nt-busy"><img src="images/_busy.gif"></img></div>
or the bdiv class needs to be added back to the styles.
I've already uploaded PR29, but I'll put the style back for PR30.
Sorry it took so long to notice the key part of your question "static pages".
Cheers
Bruce
