IMHO....if it was the website...LOTS of others would have the same problem.
Does your laptop also have the same IE8 and Vista?
Also...how large was the picture that you uploaded as your Profile pic?
Here's how to check it. Go to your Public Profile, then click on Edit Profile Picture. Right Click on your picture...then click on Properties...it should say what the Dimensions (length x height) in pixels. Or if that isn't listed...go to the Summary Tab and click on the Advanced button...and check for Dimentions there.
If it's a fairly large pic (say 600x600), that may be what's causing the problem.
Mine is about 350x250.
If that isn't causing it...check the Properties & Settings of your Monitor Screen. Minimize all open Windows so you can see your Desktop, Right Click, then click on Properties...and check the settings in there.
I DO know that if the length x width setting isn't correct at that point...you will have problems on certain websites...but not all.
Hope this helps...and I'll check back on here in a couple of days
