Mysteriously, the previewer doesn't work anymore when I click on a document. It was working till a couple of days ago. Nothing has changed on the machine; the only thing I have done is copy the data directories over so that I can migrate to another machine.
The log files don't indicate anything wrong. Do you have any suggestions on where I should start looking? The preview as I see now is attached. The previewer renders a blank image (in other cases an image of the first page what would have otherwise been rendered) hence I selected the area that the previewer is rendering as an image instead of the flash object
