Every time I get an e mail from one of my daughters, this pops up:

INTERNET EXPLORER SCRIPT ERROR

A yellow triangle with an exclamation mark in it, and this: An error has
occurred in the script on this page

Line   58
Char:    9
error 'top.DateFormat' is null or not an object
Code 0
urlmhtml:mid:/00000044/
do you want to continue running scripts on this page

Yes   No






It only comes up with her e mails, no one elses. Any clues?
