In the editor, run a sql. Change the pin of the grid to collapse the bottom window. Mouse over the grid, and the column width’s have chnaged. They should not.
I tried to replicate your issue but am unable to as I see the the column width remain the same.
Can you please send me the screen shots of how your columns look like after pinning the grid at the bottom.
I just had it happen again. Steps: run the sql, fool with the window split, collapse the data grid window, rerun the sql.
