when I am making an outline in a grid, and I press Enter to start a new sibling item below the current item - the position of the current item and the new item often jump down from the current location down towards the bottom of the grid.  Quite disconcerting.

 

Same thing happens with split (ctrl-shift-s) operations.

 

There shouldn't be any change in the vertical positions of the items in the grid when I press Enter to start a new item.

 

using PreRel7, was also present in PreRel5, which I had been using until just now.
