Of course. document.domain works if the second-level domain of both
resources is the same. Since a generated document has no second-level
domain, you cannot set its document.domain. That said, I do not think
you need to.

Eeek. Provided that `winstr' was declared before, consider

  winstr += new Array(
    '<html><head><title>my App<\/title>',
    '<script type="text/javascript">',
    'document.domain="mycompany.com";',
    '<\/script>',
    '<\/head>',
    '<body>',
    '<form name="myForm" action="default.do">',
    '<div class="textbold">Last Name:<\/div>',
    '<input name="searchFilter" id="searchFilter" size="26">',
    '<input type="submit" value="Search"><\/div>',
    '<\/form>',
    '<\/body>',
    '<\/html>'
  ).join("");

instead.

Unnecessary.

Think about <URL:http://dorward.me.uk/tmp/fullscreen.jpeg>.

if (!win || win.closed)

BTW, source code should be posted so that it can be executed as-is, also
meaning that it should not break when word-wrapped. Such (long) inline
comments should be before-comments, not after-comments.

IMO, you should wait with focusing until you have written the content.
And you should feature-test the focus() method before you call it.

You should declare _all_ your identifiers.

See above.
