BTW, it's not easy. There are at least 5 external JavaScripts and 4 external
CSS style sheets referenced in that page, and the "popup" is done using an
"onmouseover" JavaScript event handler. It calls a function called
"showtrail" in one of the scripts, which uses a JavaScript setTimeout to
call another function called "show". Upon examining the references to the
external scripts, I determined (coorectly) that it was probably the
"preview_templates.js" file that contained the code. It uses Unix-style line
breaks, which I was quickly able to replace, and here is the total scripting
in that document. The rest is up to you!
