Version 6.15 / Application Mode Desktop / NW.js Version 0.62.2

I experienced a strange thing from the previous 2-4 versions.
Query, result grid.
Formerly when I pushed Enter key on a string field (cell) a popup editor appeared to modify, or see the content.

Now the Enter key creates an extra, half empty row, and opens the editor popup window.
I can't close this editor by canceling or reopening the query. It remains. I can close it when I close the Query tab too.

Double mouse click works well, only the Enter changed somehow.
