In the following we would like to discuss a few peculiarities of working with PDF files. To begin with let us bear in mind that the acronym 'PDF,' short for Adobe's 'Portable Document Format,' comprises a large number of different versions of the format. This diversity of formats is further increased by innumerable third-party products which emulate the Adobe Acrobat Writer and produce PDF files of good or lesser quality.
Unfortunately, version 6.0 of the Acrobat Reader is not as lean an application as earlier versions were. And it is true that sooner or later, i.e. when the latest version of the Acrobat Writer has established itself, you will have to use the most recent version of the Acrobat Reader. However, the principle we want to draw attention to here has remained more or less the same from the Acrobat Reader version 4.0 onwards. An older version may possibly serve our purpose better.
