--- Comment #3 from Nikolay Sivov  ---
I remember this thing. I tried to fix it once and it turned out it's not
possible to properly maintain state imagelist because some applications rely on
it not being destroyed (as i remember some app used imagelist from one treeview
in another and it broke once i started to release it).
