title: Image editor colour problems (transparency?)
body: <p>D7: I created an edit box component which only accepts integers. I want to create a buttonbar icon for it based on TEdit.</p>
  
  <p>TEDit shows "ABC" and a cursor on a white background. I copied and, pixel by pixel, changed ABC to 123. However, while TEdit shows a white background, mine shows gray.</p>
  
  <p>The pixels are definitely white but show up the same colour as the background. Can I have set white=transparent somehow?</p>
  
  <p>Nope, I filled the white with lime green &amp; saved everything but it still shows up gray on the button bar.</p>
  
  <p>Any idea what I am doing wrong?</p>
  
  <p>(and any hints on the best way to create images? use built in tool or external? or any great web sites with lots of free buttons?</p>
