Encrypting the web

Cos I'm a bit of a thicko about this - now i'm on the https version, how do i stop the prompt "do you want to dispay secure & non-secure blah blah" every time I refresh?

(Using Explorer through work so no choice here...)

• When you receive the error message, click Yes.
  
• In Internet Explorer, go to Tools, Internet Options, click the Security tab; make sure that in "Select a zone..." window that Internet is selected.
  
• Click Custom Level and scroll down about half way to "Display mixed content" in the Miscellaneous section.
  
• Change it from Prompt to Enable.
  
• Click OK, Yes, and OK. The change should take effect immediately.
