Hello IMHO the reproduction of the bug is difficult to describe because of the necessary selections-deselections.
Below is a simpler procedure to reproduce with version 3.5 or Version 3.6.0.0.beta3 (Build ID: 3e2b862) 1. File> New> Presentation 2. Add some text in the Text Frame (where it says "Click to add title") 3. Deselect the Text Frame (for example click on "Click to add text") 4. Select the Title Text Frame (blue squares) and delete it 5. Undo 6. In the Task pane, try to change something, Layout, Master page...
