Bug 1397

when you click on a link to a directory, the tree panel gets
out of sync with the directory structure and sometimes the
tree display gets garbled. an easy way to cause this to
happen is to click on the /usr/src/linux@ link and then try
to display some of the subdirectories in
/usr/src/linux-x.x.x. sometimes nothing happens, sometimes
/usr/var is expanded. the results are unpredictable.
resizing the tree panel seems to redraw the tree correctly.
i'm not sure what the intension is re links but a couple of
times i saw the link expanded and then the target expanded
when the + was clicked on. when you try this on
'/root/desktop/home directory', sometimes the hidden files
in root appear even though hidden is off. the names in the
tree rarely correspond to the file name in the window title
and the contents on the right panel are rarely correct. the
highlighting of the selected tree entry also quite often
goes wonky leaving multiple selections of various types
displayed.
