button issue

[testLED]

Hi guys this is daft I know!!!! I'm sure its staring me in the face but I just cant find it.

Basically if I Compile and run my very basic app which currently consits of a created background and an exit button. when it appears on my screen and I maximize it my button stays in the same position. What I mean byt this the button is on the bottom right of the app but when I hit the maximize button it end up in the centre.

Any help guys. As you can guess I am new to all this.

I think i've sussed it. Basically anchoring to the correct screen position. I think thats it anyway. Well it works..
