Upon a closer reading of your previous post, I'm not sure it really helps
us. My first reading of your post was that you were suggesting a 3rd party
viewer. But it looks like you're just suggesting the PowerPoint 2003
viewer. I think that my user is already running the PowerPoint 2003 viewer,
and ALT+Tab is not pausing the presentation.
The presentation is very complex, involving videos and timed slides. When
ALT+Tab is used to switch applications, it's like the presentation resets
when the user comes back to it. So if a user is on slide 23 of 57, then
ALT+Tabs to another application, and finally returns to the presentation, it
will start over from the beginning.
The best we've been able to tell her so far is to right-click and check the
slide number before using ALT+Tab to switch away from the presentation, and
then after switching back into the presentation she can again right-click
and jump to the appropriate slide. Not ideal, but it should be workable for
her.
