Print Preview Not Working

I am trying to use the print preview button in writer, and for a few seconds, the screen reads: Generating Preview... But after about three seconds the screen goes blank with no preview at all.

I have been experiencing this on the following browsers: Firefox 2, Firefox 3, Chrome, IE 8.

I realize that many of these browsers are not supported, but Firefox 2 should be supported according to your documentation.

As a side note, the preview was working fine yesterday from my home PC.
