camera control : stretch-out effect?

Hello,
I am making 3d walkthrough project . I am using walkthrough_template.blend file downloaded from blender3d.org. However, after I start game engine, when the camera appraches to an object - door, wall, etc- it stretches out. How can I get rid of this stretchy effect?
Please help

Zoom the camera before pressing “P”…

Thank you million times

No problem mate, it bugged me alot… Although I think youll have to zoom out again when it’s an .exe …
