 I didn't mean to highlight the tab, but rather to give the green triangle
 run button a backlit yellow sun glow when the Preview tab was switched to
 -- trade out the icon, then trade it back once the rendering was done.

 If the computation were relatively cheap that could be ok, but since it
 can be expensive I'd vote to stick with the user-initiated approach. (just
 make it more obvious)

 Along the line to make it more obvious: how about if the initial preview
 document loaded a dummy graphic which had a picture of the green triangle
 button circled and an arrow pointing NW saying "click up there to generate
 preview".
 ?
