GMAX viewport query

Hi guys

I've just started down the road of learning to model on GMAX. Everythings been going well until I hit this little issue. I used the slice tool to start doing my cockpit windows and my wireframe ended up looking a bit odd as seen on the pic highlighted in white. I don't know if its a view setting of some kind that i've missed or set wrong. Only happened with the area I was working on, not the orange section behind the cockpit area. If anyone has a solution or info about this I will really appreciate it.

Regards
Allen

I'm not sure why that would happen and SOH compressing the image down don't help..
