I have my taskbar set up with the normal icons on top in the first toolbar.
Added a Game toolbar, which has one row.

Tried to add a second row to it, as the first row became full.
Several tries later in several ways, I failed to do this.

The Game toolbar keeps reverting to 1 row, or does not accept second row despite showing 2 rows (more icons added are put behind the '>> extended view').

How can I make the Game toolbar actually use 2 (or more) rows?

Thank you,
