WORD 2007 外接程序菜单，调试正常，正常执行就无效？哭

我做了一个给WORD添加手绘图片的插件。
调试的时候一切正常。
但是正常执行的时候就出现问题。using System;

}以上代码 调试的时候正常。
我对WORD里的多种对象添加按钮。
最主要的是 TEXT 和 TABLE TEXT 两个
就是WORD光标处在文本位置 或者 表格里的时候 右键菜单
会出现 手绘签图字样。  TEXT的时候后边跟着一个英文的句点。  TABLE TEXT 里右键菜单 出现的是 手绘签图，后跟一个逗号。 表示这两个菜单的不同。调试的时候任何位置都可以成功调用 对话框去绘图。但是不在调试状态， 直接启动OFFICE WORD的时候   虽然在文本和 表格里 都能正常出现菜单。
但是只在文本处出现的菜单可以正常显示对话框。  而在表格里右键菜单 点击 后毫无反应。
我加了一个 MESSAGEBOX   表格里的菜单动作都无效，连MESSAGEBOX都不显示。不知何解。求教大侠。
