Hey, I seem to be seing similar issues when putting a GWT application in an IFrame and then removing the IFrame. It looks like the entire GWT application leaks. I saw your bug report in the bug tracker of GWT. I added my comment there with a suggestion on how they could maybe fix this issue without impacting the few that would want to install a onwindowclosing handler that calls setMessage. This will ofcourse need a fix in GWT (the sooner the better since we are leaking about 40MB everytime we close the IFrame, and unfortunately we need to do this often in one browser session). David
