If i use the window method focus(), the sandglass will stay forever and the page
can't be printed because loading will never finish.
If i omit the focus() method it works well.

Examplpe focusError.html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Unbenanntes Dokument</title>
    <script language="JavaScript" type="text/javascript">
    <!--
	  function doPrint()
	  {
	    printWindow = window.open( "", "print",
"toolbar=no,location=no,directories=no,status=no,menubar=yes,scrollbars=yes,resizable=yes,width=250,height=200");
		if ( printWindow )
		{
		  printWindow.document.open() ;
		  printWindow.document.write("<html><body>Something to print</body></html>") ;
		  printWindow.document.focus() ;
		  printWindow.document.close() ;
		}
	  }
    -->
    </script>
  </head>

  <body>
    <button value="print" onClick="javascript:doPrint();"></button>
  </body>
</html>

Reproducible: Always
Steps to Reproduce:
1.Load the example focusError.html into Mozilla 1.8a4
2.click to the only button
3.now try to print the page
Actual Results:  
You get an error mesage "wait til loading has finished"
and the sandglass will never go away

Expected Results:  
The page should finish loading and the sandglass should go away.

Not a dupe. The other bug leaves out the third step

3.now try to print the page

which turns out to be the interesting part.

There is no function document.focus(), so this causes a JavaScript error. Thus
document.close() is never executed and Mozilla loads the page "forever".

So this is basically a programming error in your side (when you correct the
error everyting works as expected).

Still it seems to be a bug that that File|Print... is blocked in this case.

Note: When you leave out the doc.write(...) call from the testcase the document
still loads "forever", but File|Print... is *not* blocked.

This alert only comes up when you select "File|Print Preview", not "File|Print...".

Tested with a Seamonkey gtk2 trunk build from yesterday.

I think we have an existing bug on the fact that you can't print pages that
aren't done loading.
