Hi Anna, This should work out of the box - the two windows should be rendering and synchronised. How are you setting up your viewer and graphics contexts?
A a general note, if you are using a single graphics card for best performance one usually tries to use a single graphics window and have two cameras or more share this context. Is there a reason why you need two separate windows rather than a single window with two views? Robert.
