For the record Kilroy, after pressing Alt F9 a second time things just switch back to how they were, the numbering does not update.

Cheers for the additional input macro, unfortunately Ctrl-A F9 doesn't work- it updates my table of contents, and also updates my sequence fields, but not the table line numbers.

Here is a screenshot - the numbers 23 & 24 near the top are part of a sequence field and those update fine. The "En Suite Bathroom" heading is of a section I moved from near the end of the doc to near the start - you can see how the line numbers re-start from 1. The section following this one ("Living Room") continues its numbering from the section preceding it ("Hallway").

If I select those numbers, only those from "En Suite Bathroom" are highlighted. If I select the equivalent ones elsewhere in the doc, the line numbers of the whole doc are highlighted *apart* from "En Suite Bathroom" - so its as if moving sections is causing the document to then treat them separately.

Does anyone know how to prevent this (or easily counteract it)?
