Every once in a while my attempt to edit a question fails.  I make an edit, click the "Save Your Edits" button, the button becomes disabled, but the refresh of the page never happens and the edits don't take.

For instance, I can't edit [this question][1].  I've tried several times over the last couple days, so it's not just a one-time glitch.  Anyone else have a problem editing it?  If not, why can't I?

Per John's comment, I tried clearing the cache in Firefox 3.5.5 and I tried it in IE8.  Still no go.
