After copying http://boox.sitaphi.com
/, and unzipping the file, I finally have mamaged to gain access to the pdg files I downloaded previously. Many, many thanks, Yuri
! The funny thing is that when I click on the booX viewer icon, I am presented with an indecipherable text, which no amount of fiddling with the decoding options offered by Micro$oft can make legible, and then asked to choose between «Yes» and «No». Cautious as I am, I, of course, choose «No», and am then sent directly to the viewer, which has a large number of options in the toolbar, all of which are explained by a groups of question marks, either two or four at a time ! I really do wish I could read them, as there are certain adjustments, regarding such things as degree of text magnification, which I should love to be able to make ! But the most important thing, of course, is that I now have access to the dictionary. If only my Russian were better !...
