Having technical problems? To use the resources on MathsNet-GCSE you should be
using a modern browser that has Java, JavaScript and Cookies enabled. Your current
settings are shown in the next box...
If you are having problems running Java applets or have been directed to this page via the
JAVA ERROR message then please be aware that there is presently an incompatibility with Sun Java 6
update 13 (1.6.0_13) which sometimes prevents Java being displayed properly on pages even
though the front screen says it is enabled. To solve this problem on a PC go to Start >>
Control Panel >> Java >> Advanced >> Java Plug-in and switch off "Enable next generation
Java Plug-in". Then restart your browser.
The following tables show how to turn on Java, JavaScript and Cookies for the
main browsers that are currently in use on the Windows platform.
Internet Explorer 6/7/8
Turn Java On
Go to Tools >> Internet Options >> Advanced and scroll down
the list until you see Microsoft VM or Java (Sun).
Make sure at least one of the options directly below that heading is enabled.
If nothing works then follow the instructions at the bottom of the page.
Turn JavaScript On
Go to Tools >> Internet Options >> Security >> Custom Level and scroll
down to the Scripting section. Make sure that Active Scripting
is enabled.
Enable Cookies
Go to Tools >> Internet Options >> Privacy and change the setting to Medium or
Medium High. If you use a "firewall" you may have to change settings there too.

Turn Java On
Go to Tools >> Options >> Content and tick the Enable Java
checkbox.
Turn JavaScript On
Go to Tools >> Options >> Content and tick the Enable JavaScript
checkbox.

Google Chrome 2.x

Turn JavaScript On
Currently, JavaScript is always enabled in this browser.
Enable Cookies
Go to Tools (the spanner icon) >> Options >> Under the Hood and select with the Allow all cookies
or Restrict how third-party cookies can be used option. We recommend the latter.
If any of the above Turn Java On options do not work then it may be that you do not
actually have Java installed on your computer. In that case download and install the latest
SUN version.
Apple Mac Users Please Note
MathsNetGCSE makes extensive use of Java and JavaScript technologies, and there are issues with
LiveConnect (which provides links between Java and JavaScript) on Macintosh computers running
Mac OS X versions 10.2.x or earlier. Version 10.3.x or later should be ok.
