build number:2.6.0.v20100521-0630

steps to reproduce:
1. insert customer tables
2. set page-break-internal to 40,45,50 and see their effects

expected result:
cut page by 40 rows, 45 rows and 50 rows

actual result:
40, 45 works, but 50 shows as the same as 45, set 46 and shows the same as 45 effect
if layout preference is set to fixed-layout, the pagination is based on page-size and page-break-interval.
close,page-break-internal doesn't work if the interval number larger than one page can show
