	I ran into the same problem.  Here's the solution, first
	when you 'tabuild' the taccess unit, it assumes the max number
	of records is 1000.  So your page sizes are wrong for anything
	over that.  What you need to do is run 'tabuild /W+ file.typ'.
	Then when the configuration screen comes up select the max
	number of records as something like 32000.  There's little
	overhead for large number and it'll sure save a lot of headaches
	later.  You can also play around with the entries per page and 
	page stack size variables if you want.
