For whatever reason I cannot access more information at the bottom of comments written...When I press more, it?

It appears after the a question is closed you cannot Comment on our own answer but you can comment on other peoples answers. A rectangle box appears but you cannot enter text.

That means if you get best answer for someone when you click comments to give them more details you cannot. I asked this question a few days ago. Under the old format your could.

You should make sure your are using an up to date browser and you have cleared out your temp files and cookies using something like CCleaner. Other than that it may be a bug the Yahoo people have to work out.
