Desktop 10.0 点击文件菜单出现死机或导致软件响应很慢，如何解决？

### 原因：
连接internet时使用了代理服务
###解决方法：
这是一个bug,编号:NIM057271。
> NIM057271 - File Menu ArcGIS Online objects within ArcMap do not respect proxy values. Any organization with traffic forced through a proxy will not be able to use the "Sign In...", "Add Data", or "ArcGIS Online..." objects. Affected clients may crash or hang when performing any operations associated with the File menu.
Description: Opening the File Menu causes a significant delay when connected through an internet proxy.

需要打补丁解决：ArcGIS-DT-10-FileMenu-Patch.msp，补丁下载地址及相关说明请参见技术文章：
