If I create a new website in VS2008 and drag a TookitScriptManager control (either from the Ajax Toolkit Apr 12 2010, Stable version 3.5.40412.0 or from the November 2009 version 3.0.31106.0) on to the default.aspx page then run it using Internet Explorer 7 as the brower then the iexplore.exe process increases it's memory usage by just under 2Mb every time I refresh the page. If I change from debug mode to release mode and open the same page in Internet Explorer 7 then the memory usage increases by just under 1Mb every time I refresh the page. The latest version of Firefox (3.6.3) exhibits the same memory usage increase but reclaims the leaked memory periodically so it never becomes a problem. IE8 does not exhibit the problem presumably because it is doing more aggresive garbage collection after every page is unloaded.
I think it would be much better to fix the memory leak rather than rely on people using the very latest version of a browser in order to clean up the memory leak for them. There are still a lot of people out there using IE7.
Comments: We tried to reproduce this issue with drip tool but we could not. We are closing this issue for now if anyone has more information to reproduce this issue then user may reopen it.
