There a lot of web browser products out there and Eureka has not been tested with all of them. Also even if Eureka has been tested with a particular browser, there are lots of installation variations that can affect how Eureka works.
Mozilla Firefox is a popular web browser blablabla
Microsoft Internet Explorer is a popular web browser blablabla
Google Chrome is a popular web browser blablabla
Let's check your browser now. The following is an example of a figure:
What you should see is a green panel on the left and a black panel on the right of the figure. If you do see this then your browser is handling applets correctly.
If that is not what you see then here is a list of possible causes:
You will probably be warned by your browser the minute you try to display an applet that you need to install the Java plugin. Follow the instruction given by your browser to get it installed.
Your browser will probably display a warning that an applet is trying to display itself. Follow the browser directions to enable it to be displayed.
Fonts (the characters that you see on pages and figures) are supplied by your local computer system and not by the web server. This means that how things look depends on your computer and not on Eureka code on its web server. This really means that Eureka can't control how fonts look and, you, as the owner of your local computer, might have to exert some control. Eureka has tried to minimize this problem by using as few fonts as possible and only using fonts that are typically available
Eureka does require special fonts for mathematical expressions so these fonts must be available.
The fonts that Eureka looks for are:
This is a cursive (handwritten appearing) font that Eureka prefers for text. If you have Microsoft Office installed you will probably have this font.
This is a cursive font that will be used if MV Boli cannot be found. It is almost universally available and is an adequate backup for MV Boli.
This font has most of the mathematical symbols that Eureka uses. It is required for many figures and has no reasonable substitute. If you have Microsoft Office installed you will probably have this font.
Let's check to see if you have Symbol installed. Select Exercise 1 tab at the top of the figure shown earlier. On the greenboard you should see the letter x followed by a symbol that resembles a lower case e followed by a symbol that looks somewhat like a horseshoe. If this describes what you see then you have the Symbol font installed.
If that does not describe what you see then you will need to install the Symbol font. Don't worry because it will be free and isn't really that complicated.
