Howto remove grey circle with cross?

[dsteinwe]

I hope, you can help me: I have a grey circle with cross in it:

What does it mean? How can I remove it?

This is the grid-origin-point.
It’s possible to set the grid origin to any desired location (either using hotkey or with icon on right toolbar). You can reset the grid origin (to 0,0 of the global coordinate system) either again with hotkey or in the grid-settings-dialog.
