I have a wholesale site that is for approved retail customers only and they have to log in to view the prices. I'm having problems with browsers displaying error messages...

In Firefox, the problem I'm having is when they login, they're still on the https (secure) - so when they click on a manufacturer or submit a search, they get a popup security warning from their browser stating that "although this page is encrypted, the information is being sent over an unencrypted connection". This error does not occur when clicking on anything else - directly on a product, on the shopping cart, one of the information links, or a category.

In IE7, I get a little nicer warning at the top of the page stating that for security purposes, IE has blocked display of images that are not secure. This includes my heading images for my boxes.

Any ideas on what I could do to avoid these errors? Unfortunately, these type of warnings really scare customers. I'd be happy to provide account info to anyone who want to see these errors in action.

Thanks for your help!
