3D view problems.

[Svanrog]

My top left window in hammer won't render anything (the default window for 3D view)!. All the other windows can handle 3D views! What could be wrong?

As for now I'll just switch the top(x/y) and 3D views, but it looks strange.

Choose the camera tool and hit shift+T then put your mouse anywhere in any of the 2D windows and draw it towards the middle of it.

Thanks!
Man, I didn't even know that there was such a tool. I must have completely missed it.
