Positive.  Something else may be causing some confusion, but several sober

Absolutely.

Something is breaking this (example below).

Hmmm.  Would this cause that?

this line of code in workspace.tmpl: (Note the variable tag in the title 
attribute.  Reformatted to fit in 72 columns.)

 	<tmpl_if is_story><a title="<tmpl_var url>"
 	href="javascript:preview_story('<tmpl_var story_id>')"><b><tmpl_var
 	title></b></a></tmpl_if>

produces this line of html in the browser (also reformatted onto multiple 
lines):

 	<a title="'<a
 	href="javascript:preview_story(46)>tvhj.fini.net/AppDev/Linux</a>'"
 	href="javascript:preview_story('46')"><b>Linux Is A Powerful Operating
 	System</b></a>

If the "tmpl_var url" tag is not inside an HTML tag it interpolates 
normally.  But if its inside an HTML tag it does wacky stuff as show in 
the previous HTML snippet.  We tried the same thing in several different 
places in workspace.tmpl.  In every case once the "tmpl_var url" tag was 
moved inside the HTML tag it started substituting the first part of the 
tag over again.  This broke similarly regardless of whether it was an A 
tag or an INPUT tag.

(Incidentally my template designer in this case is my wife and she was 
very miffed that she couldn't make this "mouseover show the URL" piece 
work to finish her workspace redo.  Now she has to click into the story 
from the workspace to find the site/URL.)
