I just installed WindowFX and if I try to configure it, than it displays me only the border of the configuration window. Additionally, the system tray icon is empty, like a 16x16 transparent square. But if I want to see the window preview through mouse-over on its taskbar button, it shows me the complete WindowFX config window. Can it be something with my hardware? I've got an Athlon XP 1600+, 768 MB RAM and a Geforce 6600.
