Using Zen Cart 1.3.9f

Please can someone help?

Super orders is working fine except in batch print. I am selecting the invoices I want to print but in IE8 I just get a blank page on the screen and the page print is blank.

View source shows:

<title>Output Batch Print Job(super_invoice.php :: 4 pages :: 1 copies)</title>

<frameset rows="*,*,*,*">

<frame src="super_invoice.php?oID=44364">
<frame src="super_invoice.php?oID=44365">
</frameset>
</html>

Also tried with google chrome and the invoices I want to print display fine but they all print as they appear on the screeon - list of the tops of the invoices on one page. I don't know of a setting in Chrome to print the frames on separate pages.

I have reinstalled super orders. I am reluctant to go back to a backup that worked as I have made other improvements whilst setting up that I will lose.

Help! Thanks. Cliff
