For some reason, the markup buttons seem to break after writing on a post for a while. Nothing happens when I click them. Now, I've been writing on this post for a while and it's the second version I write. Originally I wanted to make it a "Markup issues when making lengthy posts," but then I noticed the markup buttons didn't work in this short post so I wiped it and created this instead.
The buttons worked a few minutes ago, but now they suddenly don't work anymore. Clicking the buttons simply just deselects the marked text, or if you haven't marked any text, does nothing at all.
I'm using Firefox 2 with NoScript and AdBlock, but haven't had these issues before.
