I created a project using Qt+vtk+itk on vs2010 win64. I set all the<br>
dependencies on vs2010. On debug mode the program works fine but on release<br>
mode I got this error:<br>
<br>
 *QWidget: Must construct a QApplication before a QPaintDevice*<br>
<br>
Do I have to set something else to fix this problem???<br>
