Just after I installed OS X 10.3.9 I noticed that Safari was treating my zipcode differently, and causing me to get error messages from web sites. My zip code starts with a zero. Let's say it is "01234". When I tab out of the field, or hit enter, Safari reformats it to "1234", a four digit number, that gets bounced by everyone for not being a true zipcode. Has anyone else in the NE US had a similar problem? Seems very strange to me. Better, is there a fix?
