Clicking on the chat bar over a secure connection in IE 6 pops up warning message

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Problem reproducible only in IE 6 (I tried in IE 8 but wasn't able to 
reproduce it)
2. Setup https for ijab
2. Disable avatar url, all gateways, all links in tools and all links in 
shortcuts (this is to make sure ijab does not access any http links)
3. Open https://server.example.com/ijab/iJab.html
4. Click on the chat bar

What is the expected output? What do you see instead?
When you click on the chat bar, a pop-up with the message "This page contains 
both secure and nonsecure items" appears. Ideally, this shouldn't pop up.

What version of the product are you using? On what operating system?
IE 6 in Windows XP

Please provide any additional information below.
As the problem is reproducible only in IE 6 and not in IE 8, my guess is that 
it is probably because of some specific hack for IE 6 or because of some bug in 
IE 6.
