All,
I think that I found the object of my confusion. All the users are in fact shown and geographic points are generated. However, it is difficult to see this fact, at least on my installation.
The Page counter at the bottom of the display grid is NOT correct, nor is it updated correctly. The page control always shows only one page. However, if you select the Next control, other pages are properly shown.
Thus, the issue is only that the page control is inaccurate.
Regards,
Hans
