The site seems to be sluggish today. I thought it might be my home computer but I see it hangs a bit on my office computer too.
Something else I see is the radial buttons need to be selected twice. (Perhaps not every time.) I have not watched that closely.
When I have selected the "quote", "post a reply" and "edit" buttons I had to hit them more than once. At first I assumed I didn't get my cursor on the button correctly but it has happened a few times so I wonder if it is a site issue or a my stupidity issue.
