From Wang Rui, "I've encountered a strange problem that osgviewerMFC doesn't work well

with the StatsHandler. When the 's' key is pressed, the rendering
window will be halted. I tried solving the problem by commenting a
line in CMFC_OSG_MDIView::OnKeyDown() and it seems to work now.

Another improvement here is to use a thread class derived from
OpenThreads to replace the old _beginthread(). It helps a lot in
keeping a high frame rate when you open more than one MDI child
windows. And the application using OpenThreads in my opinion will be
more compatible and portable."
