[Qt-interest] Problem with sending binary data to stdin of QProcess child. There's no QProcess::flush

So what happens if you change tohe loop to be...

While ( true )
{
	if ( !f.waitForReadyRead( 1000000 ) )
		continue;
  
       QByteArray bytes = f.read( f.bytesAvailable() );
.....
}

Your bytes available value appears to be local to the wrong scope...  I
don't know it could be an email bug :)
