title: Hooks for mouse - limitations and performance
body: <p>I have some question about WH_MOUSE. From what I've read, by putting the hook into a DLL it injects processes. Does it mean that capturing the mouse will work on my desktop, menu start etc. too? And what about title bar of applications? I've seen some posts over the Internet with such problems, but don't know if they failed with something or there's some kind of limitation (or another approach).</p>
  
  <p>I also have a question about performance between WH_MOUSE and WH_MOUSE_LL. I found somewhere that the WM_MOUSE is faster than WH_MOUSE_LL, but is it really noticeable? If so in what situations it can slow system that much that we can notice that? If I want to record only clicks of the mouse and keyboard would WH_MOUSE_LL be efficient?</p>
  
  <p>Thanks!</p>
