Splitting the screen issue.

This happening for first time. When I split the screen with the cursor at the corner of the screen, the new screen becomes with starting project. I mean it doesnt makes two screens for one project. I know its really noobish question and issue but if u help me i’ll be really glad. Thank you already =)

the new screen becomes with starting project.
What does this mean ?

Show us something. Don’t let us have to imagine what may or may not be happening
