I have added several items on the dude and worked fine for a while, but then 1 day we had a problem with the electricity and the pc got shut off in 1 sec.

before that I was closing and opening the program without problems, and all elements were present on the dude map.

after the electricity problem (black out) we lost all the elements we introduced ... is there a way to save the map/elements to prevent such a problem ?

thanks
Gianluca
