1.8.0 - Can no longer focus dialog without the mouse

[cv4x]

Previously, while inconvenient, you could press tab twice after opening a dialog to focus the first widget (and then start typing in a text box, for example). As of 1.8.0b1 you can no longer access the widgets in a dialog without using the mouse. Ideally the first widget should be focused automatically, or there should be a property in the dialog object to indicate which widget to focus.

This issue is still present in version 1.8.0
It is also now impossible to submit or cancel a dialog box with the enter or escape keys.
