You probably just used mv to change its name; this is allowed.  What you
can't do is to *move* the directory into a different directory without
superuser permissions.  In order to achieve the same funcionality, I 
have to create a new directory at the location where I wanted to move this
one and then move all the files to the new directory, finally I need to 
delete the now empty directory.  Note that no such contortions are needed
on BSD systems;  I need only type: mv dir1 dir2 & the system will cause dir1
to become a subdirectory of dir2.  On Sys V, I just get the error message,
mv: directory rename only - even though I own both directories & have chmod 
777 on both of them.

I repeat, this is a pain.

It should still let me move my own directories around.
