Results In Lagged Scrolling In Internet Explorer & Google Searches
Causes lagged or “jerky” scrolling in Internet Explorer 7-8 when more than 10 search results are set to display using Google.
This is only present in IE versions 8 and lower and specific to Google search. Other search engines (Yahoo and Bing tested) do not exhibit this behavior. This video provides an example of what this looks like using a web security enabled proxy and then using proxy with no web security.
Until we upgrade to IE 9/Windows 7, this is something our users will have to live with. Fortunately, most of them are not even aware you can change search preference in Google to return more than 10 results per page.
