Thanks for the reply. A hint on how to specify the elevated permissions would be appreciated... (Weird: when I build and run the project -- from the debugger -- on a different computer, the app does not have elevated permission. Trying to figure out the difference between the two computers. I have this code in a handler for the MainPage Loaded event:

Msgs.Text = string.Format("{0} ElevatedPermissions", (Application.Current.HasElevatedPermissions ? "Has" : "Does NOT have"));

)

The OP contains the exception I see when attaching the debugger to the browser. Certain properties of the FileInfo appear to be unavailble -- Attributes, Directory, DirectoryName -- when running outside of the browser.

I have an SL 5 app that the user can drop files and directories into. When launched from the debugger, it works as expected. When I try to use the xap in a page on a remote site, I get a Security exception. foreach (FileInfo fi in files) { // _files.Enqueue(fi); if (fi.Attributes == FileAttributes.Directory) Attaching the debugger to the browser, I see: +fi.Attributes 'fi.Attributes' threw an exception of type 'System.Security.SecurityException' System.IO.FileAttributes {System.Security.SecurityException} "File operation not permitted. Access to path '' is denied." UPDATE: Some properties of the FileInfo object are available, but not things like Attributes, Directory, DirectoryName. 1) Why does it work when started from the debugger? 2) How can I get it working outside of the debugger? Thanks for any insight....

It looks really cool in the demo... I've installed it on two computers (VS2010 Ult. provided by work, fortunately). - Performance is woeful; when a breakpoint is hit, it takes a considerable amount of time to display the canvas and render a bubble. - It appears F10/F11 don't work in the debugger canvas, I have to click on buttons in the button bar - Trying to step into a method may or may not bring up a new bubble. - Breadcrumbs at the top of the bubble appear to not work. That is, I can't navigate up the call chain via the breadcrumbs. Great concept, but maybe not ready for prime time.
