I have a program that exits just fine when you close it manually, but
throws an unhandled exception when I try to log off windows. It
suggests I enable the JIT debugger, but when I compile the program in
debug mode and enable JIT debugging it closes fine, though the logoff
process is aborted. I am using a couple of activex controls that .net
generated wrappers for, so I don't know if that has anything to do
with it, but my program closes fine manually and afaik windows calls
the same event when its trying to close a program.
Thanks in advance,
Luke
The text of the exception is:
System.NullReferenceException: Object reference not set to an instance
of an object.

I realize this is all very general but if someone could just point me
in the right direction I'd be grateful.
