How to stop flickering?

[Steve W Choi]

I have copied Vtk MFC project to another PC,
then compiled in Release mode. This time,
it didn't flicker.

Now I remember that I didn't have flickering
problem on my PC before reinstalling Win98
a couple of days ago.

After reinstalling Win98, flicker problem
suddenly emerges. I wonder what went wrong?
