Dear ns-users, If I change a tcl file in the /tcl/lib directory (e.g. ns-default.tcl) and recompile ns nothing happens. I read the archives where I found a pointer to the solution of this problem (http://www.isi.edu/nsnam/archive/ns-users/webarch/2000/msg01923.html). However the pointer doesn't work anymore. Can anyone please give me the solution? Thanks, Onno
