fckeditor和谷歌浏览器不兼容的问题

原因是它读取浏览器版本时报错，最简单的改动方法就是去掉验证，即在FCKEditro.isCompatible（）代码中增加判断有AppleWebKit串就 return true;
private boolean isCompatible() {
String userAgent=request.getHeader("user-agent");
if(userAgent==null)
return false;
userAgent=userAgent.toLowerCase();
if ((userAgent.indexOf("msie") !=-1) && (userAgent.indexOf("mac") == -1) && (userAgent.indexOf("opera") == -1)) {
if(retrieveBrowserVersion(userAgent)>=5.5)
return true;
}
else if (userAgent.indexOf("applewebkit") !=-1){
return true;
}
else if (userAgent.indexOf("gecko") !=-1){
if(retrieveBrowserVersion(userAgent)>=20030210)
return true;
}
return false;
}

不过这种改动不能保证后续代码与浏览器的兼容性，不如用新版.
下面的是需修改文件的源码
