1. I'm not seeing that problem in 9.0.1 with a SlideShow, no matter 
whether the Screen Environment is Working or SlideShow. Even if the 
cursor is inside a Text cell, if I use the down-arrow to go beyond that 
cell, I get as usual in any notebook the default, namely, an Input cell.

2. It's not clear exactly what you're trying to do here. Certainly the 
following works (where I've had to use the FullForm to paste as plain 
text into this reply):

   v={{Subscript[x, 1],Subscript[x, 2],Subscript[x, 3]}};
   w={{Subscript[y, 1],Subscript[y, 2],Subscript[y, 3]}};
   Subscript[v, 4]

> 1. In previous versions to create a new input cell on a SlideShow 
slide, I could just hit the down arrow until the horizontal cursor 
appeared indicating I was not in any slide, then type in input. To 
create a text cell I had to explicitly ask for it. In 9.0 it seems just 
typing now creates a text cell which cannot be evaluated and there seems 
to be nothing in Writing Assistant or anything else to create a regular 
input cell apart from cutting and pasting one from an empty 
non-slideshow document. Is there an easier way?
> 2. If I create, in a Math cell, two column vectors of subscripted 
numbers (x_1, y_1, z_1 etc), then want to create a subscripted value 
outside of the column vectors, as soon as I hit ctrl+underscore to do so 
the cell pops out of traditional view and the Subscript[] sources are 
visible. There seems to be no way to recover from this.
