Problems to run two JME windows

I am currently working on a project that requires we start 2 windows, totally independent each other.

These windows will share the same variables, but with different screens. That is why we need to handle 2 windows separated.

I have already tried to use 2 displays at the same videocard. I could launch the first window, but when the second one was launched, I received the following message:

Selected display mode: 800 x 600 x 0 Hz

and the first one went freezed.

Can someone help me?

Thank you all.

You will need to use AWT panels. See TestAwtPanels example (you can create two apps that use such context).

I forgot to write: Our project will run over Win 7.

Can you start one double width screen with two viewports?

Just how much data are you sharing and how fast? (i.e. could you do it as two totally separate apps with comms between them)?
