Don't know if anyone can help, but having a slight technical hitch. Did some molecular models for my masters thesis today in uni on my supervisors Apple Mac. Converted the pictures to jpg files and burnt them to a DVD. Upon taking them home, Windows on my pc doesn't seem to let me do anything with them. They are there on the dvd, but it won't let me open, move or save them anywhere. The word document files saved in the same why at the same time all work fine. Any ideas?
