Question about WH_JOURNALPLAYBACK hook freezing up until mouse is moved

Windows

Hello,

I am using journal playback to emulate mouse and keyboard input. The problem is that sometimes playback getting stuck for up to 30 seconds in different places. If I move mouse, playback continues. This problem was already described in internet at social.msdn.microsoft.com and answer was:

"That said, sounds like a known issue where the internal timer which handles the delay wakes the wrong thread so the synthesized message isn't detected. Generating a new message by nudging the mouse will wake the thread and allow all messages to be pumped. I believe this was fixed for Windows 7.

If this is the same issue, the only solution with the journal hook is not to return a delay from HC_GETNEXT."

My question is how to make delays then? This should not be a thread.sleep(10) in callback function because this way an application where I send commands freezes for the duration of a playback.

Thank you.
