Uploading Issues...

Now I might be flamed because I might have not been searching properly but I have been searching for almost an hour now and couldn't get a straight answer to this situation.

My problem:
When I go to upload a file to a variety of sites it will fly to 100% but continue to upload in the background (I use Resource Manager to check). Now I can confirm this laptop had Windows Vista on it Pre-Installed and when I had that for a little bit the uploading worked fine. So I'm beginning to ask myself if anyone else has this problem and may offer me the solution. Google has not done much help and searching through these forums didn't give me a answer either. I have found a few links here and there directly speaking about my issue but when I'm done reading that website I'm left still confused with no answer. I'd greatly appreciate it if someone could help me. Thanks.

I'd also like to note this can't be a browser issue as I've tried with Opera, Chrome, Firefox, Internet Explorer, and Netscape. I've even tried to make a video using Windows Live Movie Maker and tried to publish it straight from the program which even then it went to 99% and stalled there till the upload was complete.

Use Wireshark to analyse what is going on.

Update lan adapter driver if it all possible.

What do you mean use Wireshark to analyze what's going on? I know the problem and I know it's uploading still even when it says 100%, but I want it to show my the actual upload percentage, and like I've stated before this can't be an issue with just the browser Windows Live Movie Maker had the same issue

What I mean is use it to find out what is going on "behind-the-scenes" and to gain possible clues as to why this might be happening.
