FYI,
There's a bug with EnableVisualStyles(), make sure to call Application.DoEvents() right after. But this does not always work. what i found to always work is to call a separate method to start the app:

static void Main() 
{
	Application.EnableVisualStyles();
	Application.DoEvents();
	Go();
}

public static void Go()
{
      System.Windows.Forms.Application.Run(New Form1)
}

Sorry, i don't know VB. HTH.

>I found by adding:

>and defining the buttons FlatStyle property to System, this was doing it. However, I have a TabControl and, even if I see it is being styled, the Page 1 of it is having a fixed background. The TabControl doesn't have a FlatStyle property. I don't know where to look to resolve that one.
