I think everyone in this thread is using an html box. I think the original post was a little confusing because it also appeared to me that he was hacking his site but it turned out that he wasn't.
I would think this would still be the same as altering the position of the anchor.
Thanks for that work around Per. Gives users another option.

I'm glad the page anchors are working for you,
BUT:
I think you have ended up with a situation where 'two wrongs make a right' in a purely accidental fashion. You now have two contradictory positioning statements and - by luck? - you are ending up with something that happens to work. I wouldn't feel comfortable with this, since it could very well cause unpredictable effects in the future when you make other changes to the page or when the browsers issue updates.

If I were you I would remove the old 'boxes' for anchor positioning and only use the simple one-line anchor definition with style="position:absolute;left:0px;top:XXpx" reflecting the correct anchor position for each case.
And I would remove the boxes 'properly' from within the VSD program, rather than edit the code, for reasons stated earlier.

Have fun!
