i think i've posted this long ago, but i'm using build 869 and i still see this bug. the folder icon is not displayed correctly - the folder is open, but its icon is closed, and the previously open folder's icon stays open.
* connect to an ftp
* go into some sub dir
* disconnect
* use "reconnect to ..." in the toolbar connect button drop-down menu
* now ur in the dir before u disconnected. now select another first level sub dir, u'll see the contents of the dir are displayed in the listview, but the icon remains closed.
* selecting a 2nd level sub dir will make the icons work correctly.
