Hello Julie,
If your presentation has an OLE object in it, it should be listed in the
Contents tab of the file Properties dialog:
1) File -> Properties
2) Switch to "Contents" tab
3) Look for any entries listed under the "Embedded OLE Servers" heading
If you have "Linked" OLE objects, they will be listed in the same list
under the "Links" heading
