Can someone please fix the "[Last]" message link?

[AussieBill]

For the last few weeks, the "LAST" message link in a multi-page thread points to a page without messages, just the headers and footers of the page.

This sometimes occurs when clicking the highest page link as well.

I guess that the forum software thinks there are more pages than there actually are and points to a page higher than the real last one.

Thanks for a great forum!
