TOC third page problems

Question

Our TOC entries look like this:
Chapter 1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1
HOWEVER, if the TOC goes past the second page, they lose the leader dots:
Chapter 99 Florbling the Gromitz     99-1
(No, we don't really have 99 chapters!)
In my vast ignorance, I have no idea how to fix this. In their (presumably less vast) ignorance, neither do my Frame "experts" in-house. I've wandered around menus and Help without making any progress.
I'm running 8.0p266, non-structured.
Thanks in advance for any insight!

Answer 1

What is the Master Page for the initial TOC page?
What is the MP for the third page?
(the 2nd page should be immaterial to the problem)
So, if I do the Format > Page Layout > Master Page Usage thing on the third page of the TOC, I see (faked as text);
Use Master Page:
Right/Left is selected
Apply to:
Current Page (v) is selected
Even (Left) and Odd (Right) are selected
Second page is the same; first is the same except "Custom: First" is selected instead of Right/Left under Use Master Page:.
If the 3rd page is using an MP that differs from the 1st & 2nd pages, what is the layout of that page?
Um...so I assume it's using Odd (Right). How do I tell what the layout of that page is? I go to View/Master Pages, and Right looks the same as Left to me.
With the TOC.fm file open to frame, on page 3, can you hand-type a TOC entry that gets the proper dotted tab leader formatting?
No. On page 2, I can type xyz<tab> and get leader dots; on page 3, no dots (and the tab does nothing visible).
And please confirm that the "xyzzyTOC" paragraph types that are failing  on page 3 are the exact same pgf fmt names that work on p1 and p2.
Yes. That's what I meant about adding entries *earlier* that push entires onto page 3 -- the same entries that looked fine on page 2 are bogus on page 3.
