That needs Java, which I am definitely not going to re-install (smile). > Maybe one of them uses a stupid internal structure. OpenOffice was notorious for legacy bloat, so that would make sense.

My file has 14 pp of simple text. I've now uploaded the files above & everyone can inspect them & their structure at http://www.chass.utoronto.ca/~purslow/test/ I've renamed the PDFs to show their origin, ie LibreOffice + Ghostscript. Perhaps that will allow others to investigate. I will also have a look at Cups-pdf & at Willie Wong's suggestions. PS the file is a list of books I've noted as worth reading, so it may have a wider (OT) interest than simply to solve this problem. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
