Brek,
Thank you for the email with the details.
I could reproduce the "Edit Source" issue for components and I confirm that it doesn't work in Properties View and it's a bug. I'm looking into fixing it. Note that you can still right-click on the Component and choose "Edit Source", which works as before.
Regarding Back and Forward shortcuts, I am not sure what happened. Could you try to reinstall WireframeSketcher from scratch from our website? Note that you data will be preserved.
