In the section where the page number restarts, do the following: Click Insert tab | Page Number | Format Page Numbers. In the Page Number Format dialog box, select "Continue from previous section," and click OK.
If you see many undesired restarts, you could run the following macro instead:
Code:
Sub SpecifyContinuousPageNum()
Dim s As Section
For Each s In ActiveDocument.Sections
s.Footers(wdHeaderFooterPrimary) _
.PageNumbers.RestartNumberingAtSection = False
Next s
End Sub
