bookmarklet and bookmarks

Hi.  I am using 1.6.1 in a folder off my root.

Everything works apart from the bookmarks and bookmarklet.

The address it is going to looks correct but it goes to a 404 on my root.

the address it is trying to go to is

so that is the correct address is it not?

Can anyone give me some hints as to what this might be please.  I did mention this on the end of another post but I cannot find it again so I really apologise if someone answered over there :(

It is not plugins as I added them after.  The bookmarks have never worked.
