The problem turned out to be an old one - the number of holes sizes was greater than 15.
More than 15 will work if one changes the legend to use characters instead of symbols.
I usually reduce the number of holes sizes used on a board and so never actually encountered
the problem until now.
Thanks to all who offered help,

as Brian had suggested, it would be very helpful if you could
describe how you are having these 0 mil holes reported to you. You say that
you can't see anything when looking at the Gerbers, not unexpected, how
would you see something that is non existent?
Do these 0 mil holes appear in your .DRR report? Are they in the
.txt drill file? If they appear in these files then it sounds like Steve had
the right idea.
I have never heard of such a thing but have seen lots of 0mil arcs
in Gerber generated by Protel. Seems they are generated when using the arc

Subject: [PEDA] Gerber problem
I have a problem generating gerber files for my 5 layer board. I get a whole lot of 0 mil holes
reported when I look at the gerber files however there are none on the board apart from surface
mount parts which don't usually get reported. Strange thing is that when I change something
the holes reported as 0 mil move around the board. Anyone seen this? More importantly, anyone
know what causes it? Any help would be greatly appreciated.
