Hi,

I am using Infragistics WPF 2012.2 

In my application, I use many infragistics components with the theme IGTheme. Everything works great. However, in the last week, I added a XamTabControl and setted its theme to IGTheme. It shows perfectly in VStudio XAML editor. However, when I run the application, the theme disappear and it is white. I tried to change the background color to another color and remove the color, it stays white. There is no code that is modifying the style or the theme except the xaml. On another computer, the theme is showing correctly... I've tried using Windows Classic and Windows 7 OS Theme and it doesn't change anything. Every other controls are showing correctly with the correct theme.....

Do you have any idea what could be the source of this problem?

Thank you!
