I tried to reproduce the issue that you are describing but to no avail. Attached I am sending you the project I created for this purpose. If you could modify it, so that the issue can be observed and send it back to us, will help us find the source of the problem.

Looking forward to your reply.

Hi Konstantina,

I found out yesterday night this issue occured when "Summer" Theme is used.
I sent a support ticket along with a project to reproduce it.
This issue was  initiated on the Tabcontrol thread.
I just received a message stating that it has been  resolved and will be included in the next internal build.
To reproduce set the Summer theme  in your App constructor as follows:

 

public App()

 

{

 

    this.Startup += this.Application_Startup;

 

 

    this.Exit += this.Application_Exit;

 

 

    this.UnhandledException += this.Application_UnhandledException;

 

 

    StyleManager.ApplicationTheme = ThemeManager.FromName(

"Summer");

 

    InitializeComponent();

}


Thanks,


Honore
