when clicking on the column menu, this create a menu and lots of DOM elements.
When hide this menu, and when i destroy the gridPanel, these DOM elements are still here.
Any idea ? I would prefer ask, because of my latest post was a memory leak bugfixed in the 3.1 version
So, if it's already bugfixed, i would prefer to know now.
Thanks for help
P.S : any idea for the 3.1 release date ?
