Cell execution causes slide to advance

[TomNicholas]

Executing a cell causes the slides to advance, meaning you can't see the output of your cell.

This is with the code cell a fragment and the next cell a slide.

My solution is to use Ctrl-Enter to execute the code, rather than the usual Shift-Enter.

I am experiencing the same issue. Ctrl-Enter does not seem to have any effect; although the cell is visually highlighted as selected, the code is not executed on button press. Only if I click on the cell manually, Ctrl-Enter behaves as expected.
@TomNicholas: My current workaround to simulate the expected behavior using Shift-Enter is to insert an empty code cell with slide type 'Skip' after the actual code I want to be executed. This allows the output to be generated while remaining on the same slide/subslide, until you navigate to the next slide/subslide using the Space button.
