| Technical notes |
| Browser (version) Different browsers display incorrectly different elements of these pages. For instance, the IE upto version 6 does not display the title of the header frame. I have made no attempt to remedy such shortcomings. |
| Screen display Screen layout is designed for full-screen display at a resolution of 1024 x 768 pixels. You may gain vertical space by pressing the F11 key (and you will see your navigation bars again by pressing it again). |
| Printing The files are hypertext files, not traditional text files. This means they have been designed for use on the screen, not for print. This concerns foremost a multiplicity of links to other files and databases. It also concerns the layout: many graphic presentations do not fit on a sheet of paper. Some information is coded by colors and shading. It gets lost if files are printed with a monochromous printer. Moreover, different browsers make different mistakes in printing the files. |
| Special characters The texts are replete with special characters. If you want to see them, a unicode font must be installed. ‘Arial Unicode MS’ is generally installed on Windows computers. |
| Definitions For technical reasons, no special characters are used in the popup definitions. The emergency solution used here for their replacement is unsatisfactory and not recommended for imitation. |
