If you attempt to directly modify them in the open Properties palette, they are not modified. In fact, the only thing that is modified is the 'active' view - not the ones you have selected in the Project Browser.
The even weirder part is that the Properties palette shows a mixture of properties from the selected views in the Project Browsers AND the active view (which is not selected). Scary!
This is a dangerous little workflow anomaly. Keep it in mind until the Factory fixes this up.
