dual screen mouse
Something I cannot test currently:
Is it possible to have a full screen DirectX/Direct3D application running on one screen of a dual screen monitor setup, a Windows application (or multiple) at the other screen and switch fluently with the mouse in and out of the 3D application to the windows applications and back? Or does that work flawlessly only if the DirectX application is windowed?
The last time I had a setup like this was several years ago and I remember that when I started a fullscreen 3D application on one screen and resolution and so on was changed it totally messed up the visible desktop on the other screen, too.
