Sometimes, when I update my TOCs, which are always set to realign the page numbers with a tab leader consisting of a series of dots, the numbers shift to the left and the tab leader disappears. It gives the appearance of the numbers appearing just to the right of the last letter of the item in the TOC, although I suspect it is right aligned according to some kind of tab function that allows the last character to appear only so far to the right.
Does anyone know why Word does this? It is quite arbitrary. Sometimes, when I update the TOC, the problem disappears, and the numbers flush to the right as is normal. At other times, they stay crunched up next to the TOC entries. Do I have to clear the tab stops?
