The cause of the problem is definitively the IE rendering engine: http://javascript.weblogsinc.com/2005/03/07/javascript-memory-leaks/ http://www.posos.net/page/Index.cfm?SelNavID=2708 http://msdn2.microsoft.com/en-us/library/bb250448(VS.85).aspx
Now my question is, do you think it's worthed the effort of trying to modify Common1_0_X.js to prevent the leak problem? Maybe using a solution like this one: http://novemberborn.net/javascript/event-cache (this won't work for Trinidad out of the box but we could use the same approach).
