Internet Explorer Security warning

Every SINGLE time I go to gmail a Security warning pops up and it does not give me the option of "in the future do not display this warning."

1. I'm using Internet Explorer 6
2. No. I'm not going to just switch to Firefox.
3. I don't want to upgrade to Internet Explorer 7.

It was working just fine until I reinstalled XP. So I'm just wondering if there's a registry key I can edit or something to get it to stop displaying that warning. I already tried the options in Internet Explorer but it's unchecked.

1. What is the security warning?
2. What is your security setting on IE6?
Tools (dropdown):Options (on menu):Security (tab)
(low, medium, medium-low, mwdum-high, high, etc or did you customize it)
check for mixed content (enable to stop prompting)
See if one of the options is related to the warning and select the option to stop it.

Beautiful. Fixed. Thank you very much
