I never actually used it; tonight was the first time. Before, I just activated it and set it up. Tonight was the first time I spent any time exploring it, trying to use it. Didn't even know about plugins! As soon as I clicked on "preview" there they were!
LiveWriter works; I could edit a post and publish it. It's all these links and I'm concerned that they've crept into my blog somehow. There are like 30 lines of 6 movies, each a hyperlink, all of this between the title bar and the post itself.
Another mystery...I'll see what the Support says. I might have to uninstall this and start over again. I just hope that they're not in my blog somewhere....if I uninstall LiveWriter, they'll go away!
