gui elements truncated by parent

hi, I am using popup.cs in a ScrollView. My problem is that the popups near the edge are truncated by the ScrollView. Is there a simple way to do this?

One solution seems to be using two scripts, both with OnGUI() but with different GUI.depth. But then I have to figure out how to pass the information back and forth (script A tells script B where to draw the popup and what to put in it, script B draws the popup and passes the value back to script A). Could someone give a simple example?

You can find popup.cs from here: http://www.unifycommunity.com/wiki/index.php?title=PopupList≺intable=yes≺intable=yes

Thanks a lot!
