Moving Dock problem

[nelly22]

I attached external monitor to MBP. I have external monitor in right side of MBP display so when i move mouse to right, it goes to monitor in right.

I can't move Dock to my MBP internal displays right edge by dragging dock from separator and keeping same time shift down. I can move it to left edge and bottom but not to right edge.

You can't do that, correct. The dock can't go on the right edge of a display if another display is arranged to the right of it.
