Are my problems with IE 9 or Blogger?

We upgraded to Internet Explorer 9 the other day and now Blogger is different. It's been difficult to leave comments. I have to try numerous times before it finally accepts it.

The font that shows in my New Post field is very basic, almost like code. And when I try to change the font, it's not available, like some of my new post options, Underline, Text, ect. are not visible.

Is anyone else having problems? Is it Blogger... or IE 9?

I just hit Publish Post and it's telling me, "An error occurred while saving!! Grrrrr!
