PyHook to catch mouse events

Using PyHook to record mouse events, one has to add quite a few lines to set up a hook, and as far as I have experienced, if one uses time.sleep() or some other function that spends some time doing something, the program freezes my computer completely while doing this (the cursor starts moving slowly, and so on).

Also: Ctrl+c does not work, I have to click the cross to exit the program, which is horrible when combined with the freezing mentioned earlier.

Is there a way to avoid the program freezing up? Using the win32api somehow, rather than PyHook? (I only know how to generate input with win32api, not catch output).

import pythoncom, pyHook
class record(object):
    def OnMouseEvent(self, event):
        print 'MessageName:',event.MessageName
        print 'Message:',event.Message
        print 'Time:',event.Time
        print 'Window:',event.Window
        print 'WindowName:',event.WindowName
        print 'Position:',event.Position
        print 'Wheel:',event.Wheel
        print 'Injected:',event.Injected
        print '---'
#time.sleep(1) #If I uncomment this, running the program will freeze stuff, as mentioned earlier.
        return True

recordit = record()
hm = pyHook.HookManager()
hm.MouseAll = recordit.OnMouseEvent
