Hi Brad,
XPe/ WES2009 in kiosk mode prevents and prohibits you to accessing most of the Win XPe features, i.e., toolbars, dialogs, OS, basically it locks most of the resources from the user and shows only the ones your app needs it to see. It can be done via Internet Explore or your own app.
So, most of the time I need to run my app in kiosk mode, but I also need to be able to exit gracefully from it for very special users and access OS.
Thank you,
Larry
