I have been trying to PDF some Word documents created in Russian. The resulting PDF file is terribly slow in painting the screen once opened. You can see my problem if you try to open the following document at http://www.who.dk/ch/pha/Nis/Reform/viennaviennarus.pdf
I'm using Acrobat Distiller 4.0 and opening the document in Adobe Acrobat Reader 4.0. My target group are probably using Reader 3.0. The document was created in Word 2000 and looks just fine in that format.
