Cannot select images when importing from directory

[Heiner <list heinrich-muenz de>]

There are two different import dialogues in f-spot depending on the
source to import the images from:
If I import images directly from my camera, the import dialogue shows
rather small thumbnails and file informations in form of a list and lets
me select single images to import (using [shift - left mouse button]).
But if I import images from a directory or a mass storage device,
there's a different import dialogue, which only shows larger thumbnails
with the date below them. This dialogue offers no possibility to select
single images. Using [shift - left mouse button] doesn't work.
Is this a bug, is it a feature or is there any hidden way to select
single images?

Thanks
Heiner
