When a user in group wheel types 'su', the program actually shows the
password they type and if it is not correct doesn't print "Sorry." and
stop, it just hangs.  No shell, ^C won't get out of it, and the whole
shell window must be closed to stop it.  Is there a way to fix this?

Also, what should /bin/su be linked to if:

* only users in group wheel should su to anyone,

* even if those users can't get the root password right, they
  shouldn't be allowed to switch to root,

* if they don't get it right su prints "Sorry." as it is supposed to

* and finally what should the other su.{wheel,nowheel} (whichever one
  should NOT be 'su' or linked to 'su') do or be?  Should it just be
  removed from the system or chmod'ed so nobody can actually do anything
  with it?

Thanks for all your help.
