This probably fixes bug #839 - mine time was hardcoded to 3000 in Attack, instead of using the "0 as undefined" input that other places were using. When re653e96b0ec3 started paying attention to the input parameter, this previously ignored value became a problem.

#include <QApplication>

#include "mainform.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    MyWindow *mainWin = new MyWindow;
    mainWin->show();
    return app.exec();
}
