I’ve since found out I could use Fl_Table_Row::wix and Fl_Table_Row::wiy, I had a vague remembrance they were there, but couldn’t find the article about them.

    I was gonna mention them, but really using Fl::box_dx() et al as you did should work fine too.

I came across I had used tih in my code so searched that in the manual and found the others.

    Right.

 I know I’ve top-posted, but I cant be bothered the rigmarole to bottom post.

    Yes, I assume you're using the google group web interface, which doesn't seem to make that configurable,
    so until they do (probably never), we're stuck with their top post default.

    I prefer enabling the mail gateway to google groups, so I can use my mail client to handle everything
    in a way I'm used to, using a mail folder. (I hardly ever use the web interface to the group)
