[Wine] StrongDC++ stays in process list after exit

[enst]

Hello there!

I'm running Wine on top of Ubuntu 8.10 (all updates applied) on Asus w5f notebook. Then i run StrongDC++ 2.21 under wine. Everything (connect, search, download, chat etc) works just fine, except when i try to stop StrongDC++ it dissapears from the desktop but ps ax still gives me /usr/bin/wine ~/.wine/drive_c/Program Files/StrongDC/StrongDC.exe
i can kill -9 it, but i don't like it.
how can i debug the reason why it doesn't just terminate? Not a programer, really...
best regards, Evgeny.
