LW DLL question

Hi

I set up a DLL and linked it in a C++ application.

Now I cannot shut down the application.  This means that the LW DLL is 
"still running" and needs to be shut down, in order to exit completely 
from the C++ application.

What would be a correct course of action to achieve this?  I am not 
much of MS expert, and any help will be appreciated.

For more info, this is how the DELIVER call looks like


(deliver (lambda ()
                  (format t "XS-system trace analysis started.~%"))
                "xssysdll"
                0
                :image-type :dll
                :keep-pretty-printer t
                :dll-exports '("xssys_load_trace"
                               "xssys_parse_trace"
                               "xssys_start_user_interface"
                               "xssys_test_dll_call"
                               "xssys_analyze_this"
                               "xssys_query_on_trace_data")
                ;; :environment nil
                :quit-when-no-windows nil ; To make sure that the DLL

Not really.  It is the other way around.

It may.  Let me try it.
