Reply To: Tabs to move when adjusting text box CS6

“the boxes can change by millimetres sometimes” – ah, the benefits of standardisation! My sympathies.

Off the wall suggestion – would a right-to-left paragraph or story direction, as in Arabic/Hebrew, solve the tab positioning? There could be some interesting side-effects with the numbers if you’re not careful though. I would try it out but I’m in the middle of something else right now.
