Flash causing "secure items..." warning

Hi All,

I have a flash menu on my web store .php pages and am getting a “this page contains secure and non-secure items…” in IE7 in Vista. I think this is because of the Flash menus, but thought I had taken care of this by making the codebase embedding to “https://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0

Any suggestions on how to deal with this?

Thanks, Scott
