I have a mapping package that has a lat/long locator and when I put the mouse over my house it shows a different lat/long to MapPoints locator.
Both packages are set for "WGS 1984".
I also have a GPS engine set to WGS 1984 and the lat/long from this agrees with my other mapping program.
Mappont appears to be about 30 miles out! anyone help :?:

P.S. The lat/long is in NW UK

30 miles! wow.. Doubt this will be of use for such a huge discrepancy, but see Nick Hubbard's article: http://www.mp2kmag.com/articles.asp?ArticleID=59
