Context menu does not show up on the block selection

Hi, I’m a newbie to use dhtmlx.

I use enableBlockSelection() to highlight some cells and use dhtmlXMenuObject to show a context menu. However, when I right-clicked on the highlight cell, the context menu does not show up. It shows up only at non-highlighted cells.
Is there any way to make it work on the highlighted cells?

Thanks in advance!
