--- Comment #1 from Nikolay Sivov bunglehead@gmail.com 2011-02-01 02:11:23 CST --- Yeah, I'm aware of that. As I remember we don't free checkboxes image list currently because we don't track were state image list comes from. And we can't free always because we're not responsible of freeing user image list.
All this needs is tests.
