unusual clipping in 3d view

[Nando Mogollon]

hi
some times, when i see de project in the 3d window (open GL and shaded), it appears to be a clipping plane before the camera and the model, because i´m unable to see objects that are very close to the camera....
its very weird to see...
Why is this happening?
can it be fixed?

Thanks
