	default DjVu application without prompting you for a choice.
	-Feature update: Stability improvements have been made to the ActiveX
	control for DjVu. 
	-Feature update: Copy Image is supported for NT and Win2000.
	-Feature update: The plug-in no longer displays error messages related to
	"Stop" messages for child threads. 
	-Documentation update: To customize the default placement of the toolbar 
	use the <embed> or <object> tags in the HTML text of the web page 
	as follows, TOOLBAR=top/bottom.
	-Documentation Update: To set the default alignment of the DjVu file in 
	the viewing window type the <embed> or <object> tags in the HTML text of the
	web page using DOC_ALIGN="one of nine options".
	-Documentation update: To set the default rotation of a DjVu file in the
	viewing window type the <embed> or <object> tag in the HTML text of the
	document using ROTATE=180 degrees (90 for 90 degree, 270 for 270 degree).
	The document rotates clockwise.
	-Documentation correction: Zoom in increases from 5% to 25%, then

	Then the increases occur by 100% to a maximum of 1200%. The reverse
	occurs for Zoom Out.
	-Documentation correction - Zoom selected area only pertains to 
	the Zoom in feature.
        -Document correction - The "passive" attribute, used with the <embed> or 
        <object> tags, has been changed to properly reflect that it is not a binary
        attribute. To use the "passive" attribute, use "&passive" without the 
        "=yes/no" qualifiers. 
	- Documentation correction - The <object> tag may not good for  Win98/ME 
          in combination with IE5.x, as in the following example.
		<object type="image/x.djvu" data="foo.djvu" width=400 height=300>
		<param name="src" value="foo.djvu"   >
		</object>
	  A better way to use object tag is:
		<object classid="clsid:0e8d0700-75df-11d3-8b4a-0008c7450c4a" width=400 height=300>
		<param name="src" value="foo.djvu">
	  However, both examples work properly on WinNT/Win2000/XP and IE6.x

  IV Known Issues
-------------------------------------------------------------------
  The following known issues exist for the DjVu Web Browser Plug-in:
	-Systems which use a "VGA" pallete/theme may observe 
	non-transparent backgrounds on the toolbar.
	-IE 6 SP 1 has a known issue, Q818857, which prevents the 
	control from instantiating until the DjVu file it is 
	viewing has completely downloaded.  A supported fix is
	available from Microsoft.  See http://support.microsoft.com/?id=818857.
	-Occassional rendering problems.  Observed symptoms include (a) Annotations 
	on the first page will not render (b) the image crops to the upper left 
	corner.  The work around is to either reload the page, either 
	by reloading the document or by changing pages.
	-When setting the "Page=<id>" property using the CGI-bin type arguments, the
	Page property must be set *last*.  The problem does not occur when setting
	"Page=#".
