The "Rendering Options" button in the Photoworks menu and the tool bar does not launch the rendering options dialogue box where you can adjust settings.
I have tried the following:
Unloaded photoworks add-in
Updated to 2009 release 4.1
Added another icon in the customize menu
Tried windows tricks to recover windows that have wondered off the desktop
Threatened the computer with violence.
I haven't used photoworks in a month so this has been an annoying and ill timed suprise.
