I half-noticed this before, but now I can confirm it.
Whenever I edit my blog from IE (from home), the interface is different from the one I'm used to i.e the two frames with the top for posting and the bottom show old posts. Instead, in IE, I see only one textarea for posting, after which I can't directly post-and-publish, but need to preview, then publish. I thought the new blogger interface was not so good.

But while using blogger with Netscape, it reverts back to the older interface (the better one). Why does Blogger do this annoying thing? The same url in Netscape that leads to one interface is redirected to another url (with the "lofi" uri in it) which shows the single-framed window.

Kya pain hai! One more reason not to use I.E.
