In C#, when I save a presentation to the httpresponse stream:
Pres.Save(OutputFileName + “.pptx”, Aspose.Slides.Export.SaveFormat.Pptx, Response, false);
(where Pres is of type Presentation)
everything works in version 15.11, using runtime version 4.0.30319. Upgrading to the latest version of Slides I can find, 220.127.116.11, same runtime, causes the file to open in Powerpoint with a blank screen with no slide thumbnails on the left (see attached screenshot)PPT error.png (4.6 KB)
. Toggling the “notes” button makes the slides visible, but still no thumbnails on the left. The pptx file is also 1 kB larger than the one that opens correctly.
