Marilyn, We saw this between unix and PC and one user figured out that label_font_id's were different. Thus older versions didn't recognize as many fonts as newer ones. I'm thinking this matches your description if the binaries on the two machines are in fact different versions.
Try: set label_font_id, 1 and the missing labels should show up. There are other fonts... 2, 3, 4, 5, etc.? I don't know how high they go, but I think by #5 labels will vanish in some older versions but still display in newer ones. -Seth
