How many annotations can be shown?


I was wondering how many annotations can be shown at a single location coordinate? I’ve added quite a few MapPoint annotations to the same coordinate location, but it seems like only 2 unique annotations are shown. Since only one red pin is shown for these multiple annotations (they all occupy the same spot on the map), what I did was to click on the red pin to show the next annotation. But this only produces 2 unique annotations even when I’ve added more than two.

Thanx in advance!
