Scroll Bar Problem - Name Generator

When you select the Name generator from Edit->Writing Tools the names are populated OK.
Selecting the Name Meanings tab, I sorted the column under origin. I wanted to get some Muslim names so I pulled on the slider on the right hand side of the window and when it gets to the bottom the list is only partially parsed. The control jumps back to the top if you drag outside the window. The list stops scrolling.
