I have a separate issue with the latest version - probably my stupidity but I can't sort it out. In message view the bar at the bottom used to have delete, reply, reply all and forward, which were the ones I use. Now, whenever I try to restore those actions, it tells me the previous and next icons cannot be moved. I can add the 'forward' icon, but it doesn't stick and the options revert to delete, reply, reply all, previous and next.
The idiot's guide to sorting this out please.
