macromedia flash sitedesign: Hi again

I am trying to create a scroll pane, and i think i have just about figured out
how to. Except that, when I preview it, it only shows me part of the contents.
I have made it really simple with just one picture and i can only see just over
a quarter of it, same thing happens with 2 pictures?
Can someone help? I a mo not sure what I am doing wrong.
Also- if anyone knows how to create a different colour srcoll pane.
Thanks

Not sure about the first question without more details. But about the color...
for example, you can use componentName.setStyle("backgroundColor","0xFF0000);
to change the background color. There is a list of supported styles in the
Flash help.
