Excel 2013 VBA为单个工作簿打开多个窗口

问题：当我使用excel vba为单个工作簿打开多个excel窗口时，当我尝试打开名称管理器时，excel会冻结 . 当我在2007版本的Excel中使用相同的代码时，不会发生此行为 .

我没有打开任何加载项，如果我为同一个工作簿手动打开多个窗口，则不会发生此问题 . 我还修复了2013版的办公室，以确保它没有损坏 .

我认为我的代码有问题导致问题 . 我没有看到问题是什么，并希望有人在这里可以告诉我我的代码是否有问题 . 代码运行没有问题，Windows打开后问题发生，我尝试打开名称管理器 .

我通过调试器运行代码（逐步执行它），它完成没有任何错误 . 我还确保没有可能导致问题的外部链接引用 .

环境：

• Windows 7

• Microsoft Office 365（2013版）

码：
