I have received another update. In that one, I can see that the content of the page is ok. But, the .NET version of the site, which affects that part, includes an updated version of the pick list control. I thought that this would have resolved the issue you have in Vista but it is not the case. Basically, in that version, the pick list window is defined at position 1,1, which is why you see it at the upper left. I have found that larger resolutions were causing a problem when defining a window out of the desktop area. I also found that some security utilities were intercepting that thinking it was an unwanted popup window. So, even with that new version, in Vista, the definition of the window doesn't seem to be properly applied.
