Steps to Reproduce Behavior

  1. Create the following HTML files:Default.htm:
    <HTML><HEAD><TITLE>Repro of ActiveX clipping bug</TITLE></HEAD>  <FRAMESET id="NavTree" cols="160,*" frameborder="0" framespacing="no">       <FRAME SRC= "left.htm"  id="LeftFrame">	    <FRAMESET id="Main" rows="200,20">		   <FRAME SRC="main.htm" id="MainFrame">	           <FRAME SRC="bottom.htm" id="BottomFrame">        </FRAMESET>  </FRAMESET></HTML>					
    <HTML><BODY BGCOLOR="yellow"></BODY></HTML>					
    <HTML><BODY BGCOLOR="blue"><OBJECT id=ExampleActiveXControl1 style="LEFT: 0px; TOP: 0px" 	codeBase=download/ExampleActiveX.CAB#version=1,0,0,0 	classid=CLSID:F8B07941-6D71-11D4-B702-0001031A64F6 VIEWASTEXT>	<PARAM NAME="_ExtentX" VALUE="14923">	<PARAM NAME="_ExtentY" VALUE="16669"></OBJECT></BODY></HTML>					
    <HTML><BODY BGCOLOR="white"></BODY></HTML>					
  2. In Internet Explorer 5.5, open Default.htm. The ActiveX control that is defined in Main.htm, which simply displays a red background, paints over the white area of the bottom frame.
