Cursor is below image and and spawning problem

Hi guys,

Im really a newbie in construct 2 and just want to ask you guys a few question on why my cursor is suddenly behind every sprite that i created? Before it was just fine.

And about spawning the sprite, it tried to make it spawn after clicking.When i click on the sprite, i want the previous sprite to be destroyed and the next sprite to spawn, but when i tried to do that, it will just spawn the last image instead of the next image.What do i do guys?
