Because there's not anything obviously wrong with what you posted, nor is it clear how the location and sizes got into the state they're in. All this led me to think there was more information needed.

>PageFrame.Top+Height+(BorderWidth*2)=611
>CommandButton.Top=615

Yes. I've got that.

>Why does the PageFrame cover 1/3 of the button? The bottom of the PageFrame should be 4 points above the button, but it covers 1/3.
>I guess I'm asking how do I compute the bottom of a pageframe?

Top + height should do it.

I'll have to presume it's something to do with the codemine framework, which I don't use, so don't have access to the stretchy resize control.
