usb flash drive and gam_server - can't umount

i've freebsd 7.1beta2 and gnome2.23 - all installed from cd 7.1b2
often i can't unmounted usb flash with fat32 - because drive is busy. - fstat show, that only one service read this media - gam_server. all nautilus windows with this media is close and anyone programs read this flash drive.
i read discussion but don't see any solution.
