I've seen this behavior. Unity should have a way of being more forceful about its kills after an application doesn't respond to quits for a while (or perhaps infer it when the user issues repeated quit commands).
Other operating systems offer to do the equivalent of kill -9 ("Force quit") in similar situations. Wine is smart enough to clean up wineserver if all the application processes are removed this way. ** Changed in: wine1.6 (Ubuntu) Importance: Undecided => Medium ** Changed in: wine1.6 (Ubuntu) Status: Confirmed => Triaged ** Also affects: unity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Killing the process in a terminal, or doing a wineserver -k command, can solve the situation, however there is no way to do this within Unity even after repeated "quit" demands.
