How to keep the camera horizontal

[cosmasad1]

Hello 3dconnection world,

I have a 3dconnection Spouse Mouse and am trying to use it to move around an architectural model. Imagine a model of an office building with a series of hallways and you're trying to walk through those hallways. I have the the settings set on Helicopter mode. That way when I push on the Space Mouse's knob the camera goes forward. Unfortunately though it doesn't stay horizontal. The camera doesn't stay level. Is there anything I can do to keep it level?

Is this a problem with the Space Mouse (which I understand is unsupported now)? Is one of 3dConnection's newer models better for staying level?

Thank you!
