Often while browsing samba shares i will get a
"Directory missing/deleted" message and Rox will force
the window to close.
This seems to happen mostly after playing a video over
the samba share although its somewhat random as to if
it will happen somtimes after watching 1 video or
somtimes it wont happen with a whole load, probally
causing samba to become slightly overloaded and not
respond quickly enough.
It might be worth while having Rox check a few more
times befoure giving up or adding a small few ms delay
befoure a final check.
