SQL Server 2005脚本编辑窗口不能使用Enter，Backspace, Insert等按键

Non-Aphabetic keys like Control, Enter, Backspace & Function keys are NOT working only within SQL Server 2005 Management Studio Query Window.

When i tried to change the keyboard options (Tools menu ->Options - Environment->Keyboard), An DISP_E_EXCEPTION is being encounterd.

A full deinstall (including of .Net), reboot and reinstall does not help.

Installing SP2 does not help, either.

问题描述：

在SQL Server 2005的SQL脚本编写窗口，可以输入字母，数字，各种符号，但是，不能使用Enter，BackSpace, Insert, Ctrl, Alt, Home, End等键。

解决办法：
安装最新的SP3之后，问题解决了。
