When using Powerpoint 2013, you cannot find out the contents of slides when tabbing through parts of the slide. For example, on a title slide, when you tab through slide parts, NVDA should announce the title and the subtitle. In pervious versions of Powerpoint, NVDA does announce them (such as in Powerpoint 2010); however, in Powerpoint 2013, NvDA says text boxes instead of speaking the content of this box.


  1. Open Powerpoint 2013. If you're prompted to create a new presentation, select that option.
  2. Once you're in slide list, press TAB to move to the first field, which should be title. Enter some text into this field.
  3. Press TAB to move to the subtitle content, then tupe something else.
  4. Press ESC to exit to slides list. Then press TAB to go through parts of the slide.
    Expected: NVDA announces the content of the slide such as titles.
    Actual: NVDA says text box.

Nav object info (at the title text box)

  • AppModule: powerpnt
  • Object: NvDAObjects.dynamic_EditableTextWithoutSelectDetectionUIA
  • Role: Graphic.

System specs:

  • Windows: Windows 7 64-bit.
  • Powerpoint: 2013 64-bit.
  • NVDA version: master.9525.

Yet again, Microsoft has now tried to provide an accessibility implementation for PowerPoint using UI Automation. But as usual its far from complete, yet at the same time cripples any existing support/hacks by other ATs.
A quick fix is to add mdiClass to badUIAWindowClasses so that we ignore any UI Automation from Powerpoint, and also check for mdiClass where ever we check for paneClassDC in the powerPoint appModule. this then seems to make NVDA function quite well in PowerPoint 2013.
However, adding mdiClass to badUIAWindowClasses is not good as mdiClass is a generic container window. We must at very least limit this to the PowerPoint appModule some how.

Thanks for the fix.
A related problem exists in regards to reading slide contents during slide show (see ticket #3602). Thanks.
