Grid - dropping on one grid, but appears in another

Using dhtmlxGrid v.1.4 build 70813 Standard Edition

I have three grids on the same page.

I drag from C to B. Works fine. I then drag from A to C. It appears in B. The grid identified in onDrag is grid B.

I have moved my grids around some to make sure they are not overlapping.

Don’t know if this is important, but : C starts out with one line in it, and goes then to zero after the first move. B starts out empty.

There was issue in this version of grid with d-n-d in empty grid , which is very similar to your description.
