I noticed when I load the admin screens in IE 6 under Windows XP SP2 that the tabs overlap the content a little bit making it hard to read. It is fine under Firefox. This is in the right frame.
Also noticed that if I open two instances of the admin interface (one in Firefox and one in IE) and make changes, the changes do not show up in the second browser instance. Are the changes cached within the browser?
For instance, in one browser I turned on Anti-Virus. I then went to the other browser and clicked that tab and the changes did not show up.
