The query is run. There are message some row(s) return. But without result grid.

To open result grid I have to execute EXPLAIN command for the statement, then choose result grid on the right.

I have to do it for every query run, if I need the result grid, but who doesn't?

How to repeat:
Open MySql Workbench, then run a query.

Ah, this is just because the font for result grid set to 0.
