Even more annoying than the Overview losing its settings is the People & Places window losing it. My main has close to a thousand bookmarks that are (nominally) contained in various folders. Too often, the settings revert back to defaults and all the folders are gone. This leaves all the bookmarks for a system lumped together in one place, making it impossible to see them all when trying to find the right one on the in-space right-click menu. You're forced to recreate your folders and slowly put them all back where they belong.
Since the folders are client-side, there must be a file somewhere in the EVE directory that contains them. Anybody know where that is?
