The file dialogue in Qt takes around 10 seconds to open for some reason. A good example of this is pressing the select file button in the probe station code. I think it only happens on Windows. This is low priority to fix, but would be good to get taken care of for the sake of future code.
Try using QtGui.QFileDialog.getSaveFileName in line 132 of MDataSetConfigGui. It opens immediately, but takes a few seconds to return once closed which is much less noticable.
