JBuilder光标问题的解决方案

　　大家常常说JBuilder在中文系统中存在光标错位的问题，都认为这是JBuilder的一个Bug，其实这实在是冤枉JBuilder了！大家讨论出来的解决方法无外乎两种：
　　1、将编辑器的字体改为宋体，用这种方法带来的问题是，在宋体下的英文字体实在难看，阅读起来不太顺眼；

　　2、就是将编辑器字体的粗体属性去掉，这样也影响代码的可读性。

　　其实，造成JBuilder光标错位的问题并不是Borland的错误，而是Java的宗师——Sun的罪过！大家一定知道i18n吧？在不同的区域设置中，JDK自动调用与之相对应的properties文件，而在JDK中，Sun所推出的与中文系统相对应的properties文件存在问题，在它之中没有区分英文字体的正常、粗体和斜体，从而导致了以上所说的问题，解决的方法很简单，只要将这个properties文件修改正确就可以了，修改方法如下：

　　在jbuilder安装目录的jdk/jre/lib目录中找到font.properties.zh文件，编辑这个文件并修改成如下内容：


# @(#)font.properties.zh1.16 00/10/06


#


# AWT Font default Properties for Chinese Windows

　　保存后，一切问题就解决了！

　　这种方法也适用于任何相同的问题。

　　[题外话]这种错误SUN真的应该好好反省一下了，希望以后他们做的东西能够测试更好一些。
