Hi Russell
The first thing to try is to press Alt + F11 to go to the Visual Basic editor.
Look for a folder in your presentation's VBA project called "Microsoft PowerPoint Objects"
Under that, each slide with an ActiveX control should be listed.
Or try this wee bit of VBA:
Sub LocateActiveX()
Dim oSld As Slide
Dim oShp As Shape
For Each oSld In ActivePresentation.Slides
For Each oShp In oSld.Shapes
If oShp.Type = msoOLEControlObject Then
MsgBox "ActiveX object found on slide " & oSld.SlideIndex
End If
Next
Next
End Sub
