Hey Hillary, this sure does sound a bit weird, to be honest, but let's try to detect the problem first, before we proceed.
The thing is, this shouldn't be happening. First I thought you are using the IE browser, but now I'm surprised to see this is also happening on other browsers as well.
Are you the admin of those blogs? Is it possible for you to try to do the same thing via another computer?
As for those Zemanta settings — please forgive me for mentioning this, but it seems I misunderstood one of your previous questions, which is why I mentioned it in the first place. Not that important, so please ignore.
But do let me know how it goes on another computer and if there's anybody else the admin of your blogs. I'm eager to help!
Take care & have a lovely weekend ahead!
