Can a second powerpoint project be imported into one you're working on?

[boydsthree]

My wife's a public school librarian and ran into this problem today:
one of her students opened a PowerPoint project he'd been working on
and found that somehow another powerpoint show/project had somehow been
inserted into his.
The guy swore up and down he didn't know how it happened.
No one could figure out how it got there, or how to get rid of it.
Apparently, when they right-clicked on this new show which was located
in a smaller window in the bottom corner of the origianl project, the
only options offered were the ones for normal slideshow operations.
I'm out-of-state and am trying to help over the phone.
I's appreciate any input on this?

The normal way to do this is to open your presentation, click "Insert",
"Slides from file", browse to and select the file, choose the slides of that
file you want inserted, and click the "Insert" button. If your design is
different from the one you are bringing in and you want to maintain both
designs in the same file (PowerPoint 2002 or 2003 only), make sure the "Keep
source formatting" is checked.

Can't think of any other way of magically getting slides in without copying
and pasting. Could be gremlins! HA!
