The consequence is that lightbox no longer works on these pages, as it seems when window.onload is called the 2nd time it wipes out previous event handlers.(?)

Two ideas, knowing zer0 about Lightbox --

1) Possibly there's some explicit myLightbox.init() that needs to be run?

2) find instances of 'window.onload' and change 'em to a proper listener
     e.g. in Prototype -- Event.observe(window, 'load', do_something);
     so  previous listeners aren't removed.

HTH,
