title: Problem with Z-index of the controls in WIXUI(Problem of overlapping)
body: <p>I am trying to design a dialog box for License aggrement and other dialog boxes.</p>
  
  <p>Now if I set a image(.jpg/.bmp) in background of my dialog box then the checkbox will get disappear,and it is not visible until I hover the mouse over it. And the same problem appears with a pushbutton.</p>
  
  <p>*) I first thought it could be because of the large size of the image but I also tried with smaller sized images and the problem existed with them too.</p>
  
  <p>*) I also tried with changing the z-index of the controls but this still did not solve my problem.</p>
  
  <p>Where is the problem?. Where am I going wrong?</p>
