I've written about adding an image to the checkout_processing page in a previous thread, but this issue I believe warrants a new thread because it's a new topic. In the previous thread I was asking about adding an image to the templates/content/checkout_processing.tpl.php page because I could not see it, nor any other of the default text in that file after doing test credit card payments (I'm using the PayPal WPP module).

I found out that the content in this templates/content/checkout_processing.tpl.php page does not appear when using Internet Explorer 8, but DOES appear when using Firefox. This suggests that there is probably some code that IE doesn't like in either the <root>/checkout_processing.php file or the templates/content/checkout_processing.tpl.php file. The payments do go through fine with both IE & Firefox - it's just the text & image that doesn't appear while a customer using IE is waiting for the payment confirmation page after his payment.

Would anyone know why Firefox would be able to display this content, but IE does not? This checkout_processing page is the only page where this happens - all other of my pages can be seen in both IE & Firefox. Is there something unique about this page that could be causing this?
