Hi Garry,
Well this is the first chance we have had to see an actual capture of the problem you are having.
It is obvious that your browser is not rendering the screen properly. However, you (and perhaps just a few others over the past weeks) are the only ones out of many thousands a day to experience this.
We all (Muhammad, Ibrahim & myself) all have looked at your captures, and we cannot determine from that exactly what would cause it. Neither can we reproduce the problem on any of our half dozen or so computers that we have access to. However, we are not running XP on any of them, which may or may not matter.
It "could" be the settings for your monitor. More likely, we think, is that there is some corruption of your Internet Explorer browser.
So, our first advice, and really the easiest thing to do, would be to reinstall your Internet Explorer 6 browser.
Go to the link below to download and install Internet Explorer 6 SP1. That will correct and repair any problems or damaged system files related to your browser. That would be step 1. If that fixes it, hurray.
If not, then you will have to consider your monitor settings, both your driver and system settings, and also the settings for the physical monitor itself.

Hope this helps. Keep us posted.
