FileSystemWatcher vs Symbolic Links

Question

hallo,

if I attach FileSystemWatcher object with IncludeSubdirectories set to true to a directory including subdirectories which are symlinks, file system changes made in target-directories do not generate events watched by the FSW object on the top directory.
(If I attach FSW directly onto a symlink-directory, everything works right)

Please, is there any setting or workaround to achieve desired effect? Is it possible to monitor file system changes in directory structure which contents symlinks?

thank you
