我在使用 Ubuntu 12.04 上的全屏写作应用程序 Focuswriter 时遇到了一个奇怪的问题：当我打开 Focuswriter 时，一切都正常工作，当我将其最小化和最大化一次时，菜单栏中的某些菜单不起作用，当我再次最小化和最大化时，所有菜单都不起作用，所以当我单击文件、编辑、格式、工具、设置或帮助时什么都没有发生。我注意到菜单确实打开了，但它们只是不可见的，所以当我单击帮助然后单击下面的一点时，我会看到关于屏幕 - 但我看不到实际的菜单。当我重复这些操作时，即最小化/最大化两次，行为是一致的。
我不知道该怎么办，于是我尝试重置 Unity。结果如下：
andreas@andreas-ThinkPad-Edge:~$ unity --reset

Setting Update "run_key"
过程到此停止——我等了 30 分钟，什么也没发生。
严重错误是什么意思？它与 Focuswriter 的怪异行为有关吗？无论哪种情况：我该如何修复它？
谢谢！
