  Aside from the VB freezes caused by the C1Ribbon, there is another (and probably related) issue when changing the visibility of a group in a tab in a c1 ribbon.
  
  Step 1. create a ribbon menu like this:

  Step 2. add the following code:

  Public Class Form1
      Private Sub RibbonToggleButton1_Click(sender As Object, e As EventArgs) Handles RibbonToggleButton1.Click
          RibbonGroup2.Visible = RibbonToggleButton1.Pressed
      End Sub
      Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
          RibbonGroup2.Visible = False
      End Sub
  End Class

  Step 3. Toggle the toggle button
  
  Note that the ribbon does not expand to include the 2nd group.

  Hi Kingman,

  Thank you for sharing the detailed information. This is a known issue in the latest version of C1Ribbon and has already been reported to the development team. We will let you know the updates as soon as possible.

  In the meantime, you can use a simple workaround by putting the code to set the visibility between the BeginUpdate and EndUpdate method calls. Please see the attached sample project for reference.
