Re: Strange problems with 9.0

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 downarrow 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]

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 nonslideshow 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. >
