OK, after digging a bit, I found that for some strange (at least to me)
reason, ServiceProcess references System.Windows.Forms (why a service
inherently has a link to UI stuff is beyond me; services really should not
interact with the desktop directly). For that reason, I suspect that the
unrestricted thing blows up. If instead I say "Open=false, Save=false", it
runs fine. Of course, this leads to another issue: if Open/Save are the
only properties you can set on that permission, how does it differ from
saying Unrestricted=true?
