PayPal v 1.6 insecure content warning on checkout PS 1.3.3

[Alaskan]

I am getting an unsecure content warning in IE when a customer checks out and is redirected to PayPal. If the customer does not click the button to show unsecure content, then PayPal fails to load. Aggh, that is bad!!!

If I turn OFF SSL in the PrestaShop backoffice, then no warning is given when a user is redirected from checkout to PayPal.

I searched the forums for a solution but did not find one that applied to PS 1.3.3.

I would like to keep SSL enabled on the site but can't have that unsecure content warning popping up when people checkout to PayPal.

Can anyone help solve this issue?

Thanks!

PS> I have not selected any banner logo in the PayPal v 1.6 module. So, that should not be the cause, I don't think.
