Hello,

I am using the free windows forms ribbon control Version 3.5.6.1 page here in a vb.net application.

The form which i placed the ribbon control in is inherited from

System.Windows.Forms.RibbonForm

* Form Properties are set as follows:

Me.FormBorderStyle = Windows.Forms.FormBorderStyle.FixedDialog
Me.MaximizeBox = False
Me.MinimizeBox = False
Me.ControlBox = False

* Ribbon properties are set as follows:

Ribbon1.BorderMode = RibbonWindowMode.NonClientAreaGlass

Ribbon1.MinimizeButton.Visible = False
Ribbon1.CloseButton.Visible = False
Ribbon1.MaximizeRestoreButton.Visible = False

Ribbon1.MinimizeButton.Enabled = False
Ribbon1.CloseButton.Enabled = False
Ribbon1.MaximizeRestoreButton.Enabled = False

Problem :
Still the form displays a minimize box maximize box and could be maximized minimized and resized !!!!!!!

Please help solve this issue.
