doesn't show proper availability, columns won't sort, can't dl

I'm using utorrent 1.8.4 build 16667, and pretty much out of the blue I'm having all sorts of strange issues.

First, I can't keep torrents sorted by column. As the images below show, I use the "#" column to order torrents. Every time I add a torrent, I have to click the column again since they all seem to sort by name, regardless of torrent status.

Second, downloads freeze and never pick back up.

Here's a before picture:

Here's a 7 hours after picture:

In the first I'm downloading at about 850 kB/s when out of nowhere it just stops. In the second, I also show the avail. column which isn't making any sense.

My third problem is that the avail. column isn't making any sense. It's showing how much I've downloaded, not how much is available.

Some additional information:

ISP - Cox

connection speed -

dl: 13312 kbps

ul: 1024 kbps

Router - wrt54g v5 (firmware v1.02.5)

TCP/IP patch - no

Software firewalls - none

antivirus software - avg free

utorrent settings - upnp/nat-pmp disabled, DHT disabled, speed guide says my port is forwarded properly.

edit: everything but bittorrent is working fine, I can surf the net without slowdowns, and usenet is downloading perfectly. So it's not just my connection that's the problem, unless Cox did something in the past few days that messes with bt?

Regarding the "#" column, I'm not sure what you mean. The screenshots indicate that it's sorting by the # column perfectly fine. The availability thing is indeed odd, although I've never seen it happen here before...

I have the exact same problem just that I haven't noticed the sorting yet since I don't sort mine.

The speed suddenly drops to 0 and the availability drops to only that of the peers connected to me.

The seeds seem to be still connected as netstat shows that it's still established.

Uploading to peers is still in progress just no downloading.

No pieces of the torrent is being requested from seeds or peers.

Using the same build too. 16667

If I stop and start the torrent, it downloads properly but the problem comes back soon after.

Edit: Tried 2.0 build 16666 and it works fine. So it should be some bug in the current stable.

It sorts fine, both screen shots were taken after I had sorted the column again. I just tried to make it happen again by downloading another torrent but it didn't do it.

I guess I'm having the same problem as pegasus21, I've managed to complete a few of the torrents by opening/closing utorrent now and then.

edit: I just installed the previous build of 1.8.4 and everything is working swimmingly again.

(Using the affected build) For that torrent with plenty of seeds, when you click on it and check the Peers tab, does the number of peers with 100% correspond to the reported seed count in the torrent jobs list?
