Lars:
The trick many use to work around this problem is to split tall rows into separate rows, then apply the "None" border between those rows.
If the content falls within a page boundary, it appears as a single tall row. If some part of the content falls on a page boundary, the invisible inter-row borders allow the content to split across pages.
It takes a few minutes to set up, but otherwise works pretty well...
Cheers & hope this helps,
Riley
