This sounds along the lines of:
spec_menu 0
But it is prob not releasted.
The spec_menu should be used when you can not type or change views when you are dead. When you click on your mouse buttons to switch player views, and it dosen't work. Or you press Y or U and nothing comes up. All commands normally work when you start the next round though.
It should be typed in the console, which you still ahve access to via ~.
