--- Comment #1 from Alexander Varnin fenixk19@mail.ru 2009-08-12 14:19:41 --- I'm testing barcode scanner with WinAPI application. When program starts, it waits for data from serial. When data comes, it is doing some operations. In Windows, it exits. But in Wine it hangs on GetOverlappedResult. I think it is because of previous call to WaitForSingleObject, that clears some internal buffers. That is a problem.
