;; Bug report:
;;     Goal: save state in memory of FLTK widgets
;;
;;     Clicking SAVE suggests it is saving the network and it can print the output of FLsetsnap
;;     But clicking LOAD does not print anything after it and does not set the FLTK widgets
;;
;;    e.g. clicking save
;;    
;;      rtevent:	   T 71.654 TT 71.654 M:  0.00000  0.00000
;;    SAVE: SET SNAP 1
;;    setsnap saving
;;    isnap inumel 2 8 
;;
;;    e.g. clicking load
;;    
;;    LOAD: GET SNAP 1
;;      rtevent:	   T 51.462 TT 51.462 M:  0.00000  0.00000
