Moving my discussion from a previous topic here, as the exact problem has evolved somewhat.

PIE is working on my homepage, but not in any others... in IE 8 at least. Only trivial differences in the HTML, and same stylesheet.

I wondered if various Javascript, stylesheets, etc. related to items on other pages (a slider plugin, mainly) might be interfering somehow with PIE. But it turns out that even on pages without such extras, that are virtually identical to the homepage, PIE is not kicking in.

Homepage - PIE works:

Inside page with virtually the same structure/layout and no additional slider or JS to interfere, but PIE not working:

Still investigating, but still baffled...

already replied on other thread... try replacing the following everywhere in ur css file
behavior: url(PIE.php)
with:
behavior: url(/PIE.php)
