The behavior that you report (icon appearing, then disappearing when this
"application" starts) indicates that the reader itself isn't available
anymore from winlogon. I don't quite understand what causes this though,
especially since it doesn't match with your testing.
I suggest you enable logging (see
http://support.microsoft.com/default.aspx?scid=kb;en-us;232575 and add SC to
the debug flags).
The debug spew may yield some insights as to what is going on.
