The "ide" tag doesn't show up in the Tagged list.
It might just be me, I'm running Windows Vista, FF 3.5.5
Update: Seems to be working now. I'm not sure why. Maybe because Ólafur Waage added the ide tag to this question?
it's because the question was migrated and one of the tags doesn't exist on the target site.
This gets fixed by the daily vote sync script.
On second thought, I cant see it. Firefox 3.5.5 and IE 8 (Windows 7).
I tried tagging this post with the same tags, seems to work (though I had to keep the bug tag)
