WinXP SP2 breaks Right-click Send To Mail Recipient

I can no longer right-click on a file, select "Send To Mail Receipent" and
have it open a new Outlook Express email message with the file attached.

Is this to be expected with this service pack?

Is there a fix?

Based on: http://support.microsoft.com/default...b;en-us;821403 I
tried:
1.. In Registered file types, click MAPIMAIL, click Change, click Select
the program from a list, click OK, and then click Browse.
2.. Locate and then click the file name of the program that you use as
your default e-mail program (Msimn.exe for Outlook Express), click Open,
click OK, and then click Close.
and found that MAPIMAIL does not have any registered file typ associated
with it and, while I can browse to and see Msimn.exe, it is grayed out and I
cannot select it for use.

Any suggestions?
