Incorrect view of directory tree

[and]

Leaves of the directory tree, i.e. directories that do not contain another directories, should be depicted without little icon of plus sign inside of little square placed just before the directory. This is how the most file managers do it including Windows Explorer, and also by the way FC 2007.10. (If you should identify such directories, this property is very useful.)

FC 2009.02 in Windows 2000 and in Windows XP behaves as a rule another way. It depicts this icon which indicates the existence of subdirectories in gived directory even if it contains no subdirectory and after clicking on it icon disappears.
