Why can't i click a button when in first person?

I have made a menu pop up when i press Esc but i cant click the buttons as when i try to click the buttons the mouse disappears. if there is scrip involved in doing this please do it in c#.

That’s because the First Person Controller uses MouseLook.cs to lock the cursor to the middle of the screen. I wouldn’t use the First Person Controller in the Standard Asset if I were you since it’s quite basic.

However, if you really want to keep using it, just uncheck the Lock Cursor option like the image shown right here:

thanks for the tips, it works

OMG its become clearer now, after struggling for a day to be able to click a ui button after checking all the raycasting whatnot’s and attached components seemingly correct, i now know the issue (i think) is with the FPS looking in the wrong place and can work around it - many thanks for the pointer.
