Impress: Presentation crashes when exchange displays.

Hi All!

I’m using Liber Office Version: 6.3.1.2, Build ID: b79626edf0065ac373bd1df5c28bd630b4424273, on a MacBookPro. When I click on exchange in presentation mode to switch between screens the program just state it’ll save the current file and then shut the program down. (I could toggle between screens in the previous version.)
