Hi Angus, The irritating thing with Windows is that all stdout messages get lost somewhere when using the GUI subsystem. You would have to add additional code to handle all debugging messages. Now that isn´t that hard to do, but another issue was that some shell script stopped working when linking to the gui subsystem. I cannot remember what worked and what didn´t. Maybe the mingw runtime does a better job, but you´ll have to try that out.
Anyway, at that time I´ve looked around, but there didn´t seem to be a more elegant solution. The console closing code is not that sophisticated, so that could be improved. BTW The WinMain stuff get´s added by qtmain automatically.
