Re: problem with Nam release 1.0a7 topology editor

Hi,
	when I tried to run nam (the current snapshot version, nam-1.0a8),
I got the following error.

--------------------------------------------------------------------
Cannot connect to existing nam instance. Starting a new one...
nam: nam_init "" : no value given for parameter "trace_file" to "_o2"
    (AnimControl local-create-animator line 1)
    invoked from within
"_o2 local-create-animator"
    ("eval" body line 1)
    invoked from within
"eval $self local-create-animator $trace_file $args"
    (procedure "_o2" line 12)
    (AnimControl remote-create-animator line 12)
    invoked from within
"_o2 remote-create-animator {}"
    ("eval" body line 1)
    invoked from within
"eval $self remote-create-animator $trace_file $args"
    (procedure "_o2" line 19)
    (AnimControl init line 19)
    invoked from within
"_o2 init {} {}"
    (Class create line 1)
    invoked from within
"AnimControl create _o2 {} {}"
    invoked from within
"catch "$className create $o $args" msg"
    (procedure "new" line 3)
    invoked from within
"new AnimControl $trace_file $args"
    (procedure "nam_init" line 2)
    invoked from within
"nam_init "" "
------------------------------------------------------------------------

So I figured out that the problem lies with  tcl/anim-ctrl.tcl.
I tried using the old anim-ctrl.tcl file from nam-1.0a7 and compiled nam
again. This time, the same old problem occured when I tried to create link
between 2 nodes inside nam topology editor as it resulted in the
segmentation fault. Could you please help me with this?
thanks,
