Problems to run multiple 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. Our project will run over Win 7.

Currently, I am using the following code:


Class1 extends SimpleApplication

Class2 extends SimpleApplication

Class1 app = new Class1();



Class2 app2 = new Class2();




Can someone help me?

Thank you all.
