Formatting tags on numbered lists

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)

Help, I am struggling with automatically numbered lists. My document has a numbered list in sections alternating with blocks of un-numbered text. So far so good, but...

Whenever I try to add to my list, using either Format>Bullets etc>Continue previous list or the toolbar button for numbered lists, Word insists on doing the text as a new list and giving me a tag thing (Formatting tag?) asking if I want to continue the original list or go back to nullets and numbers (err, yes, obviously I do so why ask me again??) No matter how many times I tick, untick, and retick Continue List in the Bullets and Numbers page, it still does this.

I've tried turning off Paste Options in the Edit menu and also Auto Correct/Auto Format, but nothing seems to work. Help, any ideas????
