Navigating to a html anchor tag upon login

[pepa]

I thought this would be easy.  I have setup a html anchor tag approx. halfway down the forum profile page.  Then in the Welcome etc email when someone's account is approved I have a link for them to follow to login, so it's in the form:

http://www.org/forum/index.php?action=profile;area=forumprofile#Spill  (obviously the anchor is Spill).

Problem is when you use this link to login it reverts, after you click the login button, to http://www.org/forum/index.php?action=profile;area=forumprofile

So the anchor tag isn't there after the login and they merely land at the top of their forum profile page.

Anyone have any answers for this?
