我的JEDIT每次启动都弹出帮助窗口

popkev

而且关闭这个帮助窗口的时候JEDIT主窗口也关闭了
命令行打开时会发现一大堆类似这样的东西
[error] HelpTOCPanel: java.io.FileNotFoundException: /usr/local/share/jedit/4.2pre6/doc/users-guide/toc.xml (No such file or directory)
[error] HelpTOCPanel:  at java.io.FileInputStream.open(Native Method)
[error] HelpTOCPanel:  at java.io.FileInputStream.<init>(FileInputStream.java:106)
[error] HelpTOCPanel:  at java.io.FileInputStream.<init>(FileInputStream.java:66)
[error] HelpTOCPanel:  at sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:69)
更夸张的更改GLOBAL SETTING后整个JEDIT也关闭了

using j2sdk1.4.2 + netBeans 3.5.1
