There are three processes hanging around after that
 err:dc:DCE_FreeWindowDCE [1264] GetDC() without ReleaseDC()!
wineserver and two wine threads. I did a bt on all of them: <output below>

Let me know when it rings a bell. To my inexperienced eye it appears like 
it got stuck in some IO routine.
Anyway, is this "err:dc:DCE_FreeWindowDCE [1264] GetDC() without 
ReleaseDC()!" a critical one or would the program continue if there was not 
another problem?

Thanks for your time. Much appreciated.
