That's sounds very strange.
I guess I'd like to see this first, and then we can go from there.
Can you make this accessible from the Internet and either post the URL or send it to me by Private Message?
If not, please ZIP up all the relevent files and email them to me at supportstaff AT tectite DOT com, and I'll check it out on a local machine.
Multi-page form support is quite new, so it's possible we have a bug and I'm happy to have close look at this for you.
