Mouse Cursor

I have the newest unity version installed and in playmode i dont see the mouse and so i cant edit variables in playmode.
Could need some help!

There might be a problem because you disabled the cursor in code?

Screen.showCursor = false;

It can also be caused, because you maybe changed the Default Cursor inside the PlayerSettings:

Doesnt solve the problem.The specific game cursor works and if i move the cursor to the taskbar it is there but if i move the mouse back to unity it only appears in game window.
I really need some help.
Thanks!
