Button turns invisible on Windows 7 machines without Visual Studio installed
问题 We have a window that displays fine on all of our Windows 7 development machines with Visual Studio but not on the ones without Visual Studio installed. We have a simple OK/Cancel button pair and on the affected machines the OK button is invisible but if you click in the place where it should be it still works. Here are the styles used: <Style x:Key="OptionsOkButton" TargetType="{x:Type Button}"> <Setter Property="HorizontalAlignment" Value="Right" /> <Setter Property="Width" Value="100" />
