HT and Pyro.. When I got the white screen I was locked solid.  F4 would not quit the game.  I had to turn off my PC.
Also...in the FSO Fencer and I were talking about, we were near or over A34.  Most in a multi-aircraft enagement.
I discoed about 10 minutes before hand.  I must say however...after downloading the terrain and entering the tower on
the Luzon Map I immediately got the whitescreen before hostilities started in FSO.
This time I got the standard msg from microsoft, windows will now close etc.
thanx
