Edit 2: Also just noticed that when i mouseout of the 'virtual file system' frame the lines linking each
folder/root disappear. when i put my mouse back in that frame the lines reappear.
yes 
, it is cryptically reporeted by this
+ vfs details only when needed
i saw Vista doing it, and i think it may be a good thing, because you see those "details" (graphical elements) only when you are working with the vfs.
@Pit: Read the quote above again. It is intended behavior (VISTA like).
(again in German: Dieses Verhalten ist so gewollt, es ist kein Bug. (imitiert Windows VISTA))
