Hi,
We are using the the Editor and an UpdatePanel. In this combination when running in IE9-mode, there is probably a memory leak.
Example:
Each click on the button generates almost 1M more memory in the task manager which wont go away until a reload of the page!!!

Hello Caesar,
Actually, there is no real memory leak here - just a high memory consumption. I would recommend to check the following blog posts for more information on the subject:

http://blogs.telerik.com/aspnet-ajax/posts/11-05-09/memory_leaks_and_memory_consumption_in_web_applications_part_3.aspx
The problem in this case is that both the button and the editor are in an Ajax update panel. When you click the button, the Ajax update panel recreate its content again (button and editor), but it does not dispose the old content - this is a known issue in AJAX. Unfortunately there isn't much that we could do about that from our side.
