Hi Volvick,
Please, try to set the palette of the context menu by code not by the designer.
For example to set it to be Office 2007 Blue in the form constructor you can write the following after InitializeComponent() call in the form constructor:
nContextMenu1.Palette.Scheme = Nevron.UI.WinForm.Controls.ColorScheme.Office2007Blue;
nContextMenu1.PaletteInheritance = Nevron.UI.WinForm.Controls.PaletteInheritance.None;
When you set the palette in the designer it put the settings in resource, which may cause the problem.
Please, let us know if the problem persist.
Best Regards,
Nevron Support Team
