my wife emailed an Open Office "powerpoint" and the people in her study group cannot open it up.?

I have experienced many problems with the Open Office suite. The main problem is most likely that the people she sent it too don't have the same version of Powerpoint that the presentation was created in. They need to try and download the open office version of powerpoint and then they can probably open the presentation.

Probably cause they are trying to open it up in MS Powerpoint. If it was created in Open Office then some functionality will be disabled.

They will have too download open Office too to open it.
