Acquia Marina w/IE6 & IE8 Incompatibility

Yes, I'm using Domain Access 2.0 with Domain Theme enabled. The issue isn't that a block is missing. I understand that. It's as I explained. I don't know any other way to explain it. I'll include a couple pictures to illustrate.
As for a full site configuration, what do you want to know? A complete list of all the modules? This problem doesn't happen when using another theme and based on the dates that I installed modules and the date that the problem began, I've narrowed it down to likely being a Domain Blocks/Acquia Marina issue. Combined with the previously explained phenomena with activating & deactivating the module even further reinforced my suspicion.
Precisely if its a Acquia Marina theme problem or a module problem I don't know. That's up to you technical folks:) As I've said, I've also posted this issue on the Acquia site as well.

Update:

Nonsie, I respect the fact that you should know. The issue is strange and the strangeness seems to revolve around this module. I've created an update to the issue (http://drupal.org/node/387962#comment-1314788). Perhaps you'd like to look at my entry (#4), "Result 1". Then if you still feel it's not an issue with this module I'll accept that and let it be.

Thanks.

I've disabled the Domain Theme. There was no change. The problem still exists.
I'm using the same Acquia Marina theme for all, however, I've created separate installs of them so I can later customize them. So it's the same theme, but different instances of it. I hope I'm explaining that well enough.
