A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
OK, this is what I get:
PPT 2010 on Windows 7.
PPT in edit mode on screen 1 (laptop). Presenter view set to display on screen 2 (a monitor as it happens, but could be projector).
Start presentation. I now have my presenter screen on 1, displayed show on 2
I alt-tab back to edit screen.
I move a shape and see it move on screen 2 (once I let go)
I delete some text and see it delete on screen 2 (all at once if I select a word then delete, or character by character using backspace)
Typing text also appears.
So, it sounds like I can do what you are trying to do.
Just to be awkward, I also tried it with the screens swapped, ie trying to edit on the same screen as the show (maximised or in a window). Now when I edit, I DON'T see changes in the "presenter" view (even though they update in the show I can see behind my edit window) until I switch back to the show, when it redraws the presenter screen too. Basically it looks like the presenter screen is only redrawn when it has focus, whereas the show screen updates in real time regardless.
Also, don't get bogged down with presenter view if you don't need to - you can still choose which display to have the show on even with presenter view turned off, if this makes it easier to manage your editing on one screen and show on the other.
Hope this helps, even if only by giving you another set of results to compare to.
