That method should be getting called from the constructor of
the SymBr& class on line 84 of gui/symbolbrowser.tcl:

% grep -n sn_rc_symbolbrowser symbolbrowser.tcl
83-        #call user function
84:        catch {sn_rc_symbolbrowser $itk_component(hull)  
$itk_component(hull).menu}

I would be willing to bet that your Interp does not know
that you defined the sn_rc_symbolbrowser method. You
might want to take a look at the sn_load_rc_file
in sninit.tcl to see if it is pulling in your rc.tcl
file. You should be able to just set the SN_DEBUG env
var to 9 and then look at the generated debug log
in your C:\Temp dir.
