Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Frequently when following a direct link to an answer, the answer will stay highlighted indefinitely instead of fading-out like it supposed to. This happens more often then not and gets very annoying. There are no errors or warning in the javascript console or firebug, so I'm not sure what could be causing it. Here's a screencast of it. This is happening in Firefox 3.5.

I'm wondering if this might be a firefox bug, because it stopped doing it for ~20 minutes after a restart.

This happens to me all the time on Safari (version 4.0.1, but it's happened on other browsers as well) – Kyle Cronin Jul 16 '09 at 19:41
i had been seeing this and assumed it was because i had firebug turned on. i experimented with turning it off and that seemed to fix it, but maybe i just got lucky... – Kip Jul 24 '09 at 12:59
Still broken for me in Chrome on Windows XP. See my comment in the accepted answer for bandage-fix suggestion. – Nosredna Jul 24 '09 at 18:00
Same as Kyle - broken in Safari. – deleted Jul 30 '09 at 20:13

I've narrowed this issue down to the jQuery color animation plugin - it was way out of date.

The next build will incorporate the latest jQuery.UI; I haven't been able to repro any longer on our development sites!


All sites now have this code live and I'm not able to repro a stuck background color.

+1 I know this happened to me quite often... Many times I wondered if the background was even supposed to fade. Thanks for the fix. – Ian Elliott Jul 24 '09 at 4:18
It just happened to me in Chrome. In fact, I added what must be a dupe question just now. I'll keep an eye on it and see if it goes away tomorrow. – Nosredna Jul 24 '09 at 5:05
@Nosredna - did it happen on this site? – Jarrod Dixon Jul 24 '09 at 5:07
No, it happened on SO. – Nosredna Jul 24 '09 at 5:11
ARRGG! I can repro in Safari on Windows still :( – Jarrod Dixon Jul 24 '09 at 9:56
On SO, it's still happening in Chrome (Windows XP). Has the change been rolled out into SO yet? – Nosredna Jul 24 '09 at 17:30
What if you do a setInterval and check once every second to see if it exists before you animate it? Then see if people still have the problem. Obviously not an ideal solution, but just as a sanity check. – Nosredna Jul 24 '09 at 17:39
I'm starting to thing you're the problem here Nosredna. A little fishy that it's only affecting you, isn't it?? – Ian Elliott Jul 24 '09 at 18:50
Well, everyone has always known I'm a problem. – Nosredna Jul 24 '09 at 18:55
I wonder if the animate is happening or not. Could you pop it to white at the end of the animate? Then if we saw a pop or not, that'd at least be another clue. – Nosredna Jul 24 '09 at 18:56
Hey wait. Are you hinting that you have an 'if (user=="Nosredna") {screwrandomestuffup()}' condition on your server? – Nosredna Jul 24 '09 at 19:23
@Nosredna - that's exactly what I have on dev right now; at the end of the animation, ensure the background-color is the intended color. I guess I should file a bug with jQuery.UI on this - the animate is called, but sometimes doesn't affect the color! – Jarrod Dixon Jul 24 '09 at 23:23
Yeah, you should file a bug. Get the jQuery mob looking at it. Good for everyone if it gets fixed. – Nosredna Jul 24 '09 at 23:47
I just saw the color "pop." You must have pushed that out to SO. Good work--that's much better than the permanent hang on the orange. – Nosredna Jul 25 '09 at 19:29
@Nosredna - yeah, that issue was a real pain! – Jarrod Dixon Jul 26 '09 at 7:43

Did the whole of the page finish loading properly? I've noticed that it only starts fading out when it's loaded everything including the quantserve tracker and the jobs bit. If one of those got "stuck" for you, that could explain it.

Yes I have. I even checked the headers and every request was returned with a 304 Not Modified or 200 OK status code. – tj111 Jul 16 '09 at 19:39
Interesting. I basically only use Chrome, and I don't think I've ever seen it. – Jon Skeet Jul 16 '09 at 19:42
@Jon: Have you tried Chrome on Linux. The new tab page is enhanced and cooler (I guess because it's open source). – Dexter Jul 17 '09 at 3:27
@Lucas: Yes, I use Chrome on Linux the whole time at work :) – Jon Skeet Jul 17 '09 at 6:30
I use Chrome-W and happened to me, but possibly because the reasons Jon described. – akarnokd Jul 21 '09 at 13:11
I use Chrome (almost) exclusively as well and have only seen it on meta and (I think) superuser. Never noticed it on SO. – Lunatik Jul 24 '09 at 10:00
I use Chrome on Windows and I see it very often on SO. At least twice a day. It definitely hits Chrome. – Nosredna Jul 24 '09 at 18:08
