Cannot open .ppt with 1.4.3

My function that opens a presentation has stopped working after installing version 1.4.3:

Private Function OpenPresentation(ByVal strPath As String) As Presentation
Dim flPPT as FileStream = New FileStream(strPath, FileMode.Open, FileAccess.Read)
Dim pres as Presentation = New Presentation(flPPT) 'error on this line

flPPT.Close()

Return pres
End Function

The error I receive is: Object reference not set to an instance of an object.

This function worked with 1.4.2, but stopped working with 1.4.3. Any ideas?

Dear Michael,

Thank you again for the report and ppt.
Please check 1.4.4. Color of title text was fixed too.
