Ahh, I guess I figured if I said my app had a certain bunch of permissions,
it would have those, IE or no. :-) Well, I have a couple other questions if
you wouldn't mind answering them, since the whole thing has me a bit
frustrated :-(

1) Is there any way to check just what permissions my app *was* given, then?
:-) Aside from continually calling Assert/RevertAssert

2) Is there any way to tell why, for instance, my app won't load inside IE?
I can't find anything in the Event Log but I'd really like to know the
reasoning for some of the strange things it's doing. Right now, I have it
added as a URL with Full Trust as a child of the Local Intranet group, and
it doesn't load at all. If I remove the URL and just let it run with the
default Local Intranet group permissions, it does load.

3) So, if I am in IE, and my app does have permission to access the hard
drive, I still need to assert that permission specifically, otherwise I will
just have the lousy permissions of IE, correct? :-)

Thanks a lot! -Jim
