<br />
What im wondering is the reason for this behavior.  With the modified code my text comes out properly regrardless of how much text there is be it 1 page or 50+ pages.<br />
<br />
Any help with this would be appreciated<br />
-thx

...rest of the thread<br />
Note that inside this thread I use an object which implements CCriticalSection object that I lock and unlock for each function.  Both the GUI thread and this thread calls functions on this object.<br />
}<br />
Furthermore I define:<br />
	inline void StartCapture()<br />
	{<br />
		m_bCapturePaused = FALSE;<br />
		::SetEvent(m_hCaptureEvent);<br />
		::ResetEvent(m_hCapturePausedConfirm);<br />
	}<br />
	inline void PauseCapture()<br />
	{<br />
		m_bCapturePaused = TRUE;<br />
		::ResetEvent(m_hCaptureEvent);<br />
		::WaitForSingleObject(m_hCapturePausedConfirm, INFINITE);<br />
	}<br />
