memory leak in virtual sample page.

I am using version 2.0.1-std-developer. It appears that the sample page examples/new/virtual.htm leaks memory in IE. I watch the memory using a tool called drip (http://jgwebber.blogspot.com/2005/05/drip-ie-leak-detector.html). Each time the page is refreshed the browser is using around 4MB more. If you scroll the grid and click a header to sort the columns, then it may leak 10MB.

When I tried watching the memory of IE, outside of this drip tool (now I am using Process Explorer), the memory jumps are small. Maybe the problem was just with the tool.
