问题描述
使用SetWindowsHookEx设置低级鼠标挂钩时，我发现Vista和Windows 7 RC在操作上存在差异:
如果出于某种原因-CPU使用率出现随机峰值，无论-我注册了鼠标挂钩回调proc花费的时间超过了允许的最长时间，在Vista上，我的挂钩函数仍会被再次调用，在Windows 7 RC上，我的回调函数似乎再也不会被调用.
是否可以确认这是Windows 7的新预期行为?
谢谢
Ross
When setting a low level mouse hook using SetWindowsHookEx I am seeing a difference in operation between Vista and Windows 7 RC:
If, for whatever reason - random peak in CPU usage, whatever - my registered mouse hook callback proc takes longer than the maximum allowed time, on Vista my hook function will still get called again, on Windows 7 RC my callback appears never to be called again.
Can someone confirm that this is new, expected behavior for Windows 7?
Thanks
Ross
