RunCode Problem

[Susan]

We have recently upgraded to Access2003 from Access2000. I used to have a
button in a form that when clicked would run a macro that did several things
including an action "RunCode" that ran "SubmitUC()" (see below)

Private Sub cmdUserChange()
FollowHyperlink "https://www.blahblah.com/scripts/UserAuthentication.cgi"
End Sub

Function SubmitUC()
cmdUserChange
End Function

Now when I run this macro, all other steps work fine, but when it gets to
this last
step, Access crashes and closes everytime! Any ideas what my problem could
be?? The only difference in the code itself is it used to be "http" instead
of "https".

Thanks for any help!
