usb-stick not mounted automatically 9.3

I've just installed 9.3 on my wife's laptop. With 9.2, when she inserted her usb-stick, it was mounted automatically and a konqueror window opebed and showed the contents. With 9.3, it does not work any more. mount /dev/sda1 (or sdb1 sometimes) -t vfat /media/usbkey works, but she can't write as user to the usbkey, and this procedure is not practical anyway. How can I revert to the 9.2 type functionality? Thanks Fx
