I created two toolbars

I do not speak English because I used translator
I hope you understand.

But there is a blank in the corner.

I want to have no blank like a picture.

The screenshot is so cropped it is hard to tell what we are looking at.

Please post a screenshot showing the full window.

I hope I do not have blank

Are we talking about docked toolbars on the edges of the desktop?

Positioning of those is decided by Windows itself.
