Well, this may be exactly what you're saying, but if the digits have no hinting information and one of the browsers honors it and the other doesn't, then the numbers would look the same. So maybe that it what the issue is. You'd think that was something that Apple would have dealt with in their library.

I sent an email to the OmniWeb mailing list and got a reasonably positive response.

One thing I didn't realize, too, is that even though I was using sneakypeek 13, sneakypeek 1 came out well less than a month ago. That's much faster than their old development turnaround time. So maybe they've just not gotten to it yet.
