You currently have to double-click on a row in Pulse in order to open the corresponding task or message details. This is counter-intuitive, because Pulse visually presents itself as drill-down interface that takes you from the list to item details and back again, and it requires too many clicks: Pulse should be quick to navigate in as it tends to offer me tasks I work on in-between longer, more complex tasks I solve with apps.
Please change the click behavior so that I get to the task/message details by single-clicking on a row, unless I click on the checkbox and its immediate surroundings. The latter should simply select the row. Make sure that you retain immediate visual feedback that the row has been clicked by momentarily highlighting it.
