- Which browser?
- Microsoft Internet Explorer 3 und Netscape Navigator 3
are only suitable for some of our pages.
- Microsoft Internet Explorer ab 4: Fine.
- Netscape Navigator 4: Fine.
- Netscape Navigator 6 and higher and the related Mozilla:
In the default configuration, mathematical symbols are not displayed correctly
(for a fix see below) and some
malfunctions arise in interactive tests (see the last item below).
- Opera: Should more or less be fine. Sometimes reacts quite slowly.
More details on browser issues may be found in the items listed below.
Please inform us about any malfunction you encounter.
- Pages containing formulae will look best if the following two pieces of text
are represented with the same font size:
|
Font Size Test
|
|
This shows how your browser
represents a piece of text.
|
This shows the font size the text
should have.
|
In order to change the font size on Windows systems, you can
choose "Small Fonts" in the settings (right mouse chlick on your
desktop background, then click "Properties"). Alternatively, you can change the
representation style in your browser
(Netscape Navigator: Menu "View", then choose "Increase Font" oder
"Decrease Font";
Internet Explorer: Menu "View", Submenu "Fonts").
- The applets of the Gallery only work in a browser which can interpret Java
and for which this function is enabled.
- The screen resolution shall be at least 800 x 600 pixels
(otherwise some applet windows will be "too large").
- For an optimal appearance, the
color depth of your screen should be adjusted to be
greater than 256 colors.
- The functionality of Java applets should be the same for all platforms,
at least in theory. In reality, the continuous development of both Java and the
browser technology sometimes cause inconveniences. Should
this happen, please tell us.
- You may perform a check of Java functionality
by clicking this button. It just calls a small Java applet.
If your system does not pass the test, you either
- have not enabled Java in your browser, or
- your browser cannot run Java, or
- you are behind a fire-wall or a severe proxy server which keeps Java
applets out of your local net. Consult
this page!
- In some of our pages, mathematical symbols have been represented according to the
scheme of the program
TTH (Version :1.5.5).
It makes use of the "Symbol" font. In case of problems with mathematical symbols, you might
try one of the following:
- Windows users may easily enable the "Symbol" font for Netscape 6:
As soon as Netscape 6 or Mozilla is installed, there is a file
named fontEncoding.properties on your computer
(in the Netscape or Mozilla directory, which is presumably located under Program Files\)
whose path ends with
...\res\fonts\fontEncoding.properties.
Using a tex editor, just replace the line
encoding.symbol.ttf = Adobe-Symbol-Encoding
by
encoding.symbol.ttf = windows-1252
Likewise, this may be done by running a program available at
this page.
-
Linux/Unix will find general information (including Netscape 6) on
this page.
In case of Netscape Navigator 4, you should add the line
Netscape*documentFonts.charset*adobe-fontspecific: iso-8859-1
to the file .Xdefaults
(or .Xresources)
in the home directory.
- MacIntosh users should change their Document Encoding (under View)
to "MacRoman" or "Western(MacRoman)"
(detailed information).
- All applets are suitable for
Netscape Navigator 4 (and higher) and Microsoft Internet Explorer 4 (and higher).
Some run in Netscape Navigator 3, but may cause extreme time delay.
The self-made puzzles and the puzzles in the interactive tests
do not work in Netscape Navigator 3 (due to the use of new Java and HTML functionalities
this old browser does not understand), and the online worksheets in the
suggestions for the classroom
do not always work properly with it - so, if you use this
browser, it is highly recommended to switch over to a newer version (at least 4).
Netscape Navigator 6 and the Opera browser run the applets
more or less in the desired way (althought the latter sometimes reacts pretty slowly).
Unfortunately Netscape 6 shows misfunctions in some of the interactive test
puzzles. You will be notified about these (and how to get around)
when loading such a page in Netscape 6+ or the related Mozilla browser.
