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
