Hi Jeff,
1. The blink that you see is because the page is not fully loaded and the Ribbons are shown via Ajax (when the page is loaded) and they are not present in the markup till it is loaded.
2. "Reentering the admin from another domain" should have no effect at all as the admin part in nopCommerce is one and only no matter how many stores you have and from which domain you enter it. But I am curious to check this in your environment. So you you are willing to provide us with administration access to your store (you can send us an email) and describe how to reproduce it we will be glad to check it.
