After opening the .odp file in PowerPoint, most of think-cell's functionality is lost. Some underlying chart bodies (Microsoft Graph charts) still work, but most functionality is not present (labels, arrows, Gantt chart, …).
This problem can occur, e.g., in the following situations:
In the PowerPoint object model, each PowerPoint.Shape has a Tags collection that allows to store extra information about objects. think-cell uses such tags to identify which shapes on the slide belong to think-cell (for details please refer to knowledge base article KB0073).
PowerPoint does not export the tags into the .odp file format. The information that certain shapes are think-cell shapes is lost.
Sub List_Tags() Dim oShape As PowerPoint.Shape Dim str As String Dim i As Integer For Each oShape In ActiveWindow.View.Slide.Shapes Debug.Print oShape.Name & "( " & oShape.Tags.Count & " tags)" For i = 1 To oShape.Tags.Count Debug.Print " Tag(" & i & "): " & _ "Name: " & oShape.Tags.Name(i) & ", " & _ "Item:" & oShape.Tags.Item(i) Next i Next oShape End Sub
