Jason, Afraid not. My theory was that either the master or slave camera projection matrix was not being updated when the window was resized... but I never could confirm this.
In my case I skirted the issue by doing away with the use of a slave camera in my application. I was using the slave to do an embedded viewer tied to a .NET control, but that approach is no longer necessary.
