Graphics Color in Qt 5.1.1 (Win XP)

  • I am experiencing a bizarre phenomenon with an application compiled with Visual Studio 2010, Qt 5.1.1 in release mode. When I run it on my machines at home, either a Win 7 or a Win XP, it looks fine. But I distribute to one of my users on a Win XP machine and the graph colors come out in grey scale, Has anyone experienced this? Am I missing a .dll to distribute to them? The lines and points are drawn with QPainter drawLine and drawEllipse methods. This app has worked fine for many years, evolving from Qt 3 to its recent conversion to Qt 5.1.1. I can send images, if you want to send me an email response.
