这是问题所在：我开发了一个活动文档服务器并在 IE 中使用它。活动文档有一个名为“工作”的按钮，单击它时，它会工作约 3 秒。在此期间，我无法以任何方式使用 IE。像切换标签或关闭标签。我的问题是：按钮在另一个进程的com对象中的一个组件中，为什么它会挂IE？如果我使用 ProcessXP 或 WinDBG 挂起 com 服务器，那么 IE 将永远不会做出反应，直到 com 服务器恢复。我在下面得到了 IE 的堆栈，两个都是 iexplore.exe。任何人告诉我 IE 正在等待什么？开发环境：Win server 2008 standard 64 bit/IE 8 32bit
主 iexplore.exe：
