email/different user problem

[Al]

Hi...Here's the problem;We have XP, and whenever my wife
clicks on a web link to send mail to that site, outlook
express tries to open, however, she uses Excite mail as
her email account. I don't have the problem because I
use outlook express. How does she change her user
settings to make Excite mail her default email server? I
tried going to the control panel settings, but didn't
have much luck, it only seems to offer the option of
outlook express as an email pick. Thanks for any help
you can give.
