I assume you are on the Esprit line, not the Pro. There is no easy way for the Esprit versions, what i do is transfer the file to the next computer, open the scene there and write down what bitmaps are missing. And then copy them over in a "second wave". With Pro you have the option to save a scene with all bitmaps included. Thern it is easy. All is together automatically.
