Thank you, Morten, for your help.
Close() method does work, it releases all used resources...I am not
familliar with COM (my friend wrote the dll for me), but in destroy method
(is it?) he releases odbc connection. That opened connection was the problem
I described above...
...and very sorry
about my late response, I have not worked on app which uses jawin for a while
so I was not able to test it...
Thx much again!
