Turned this issue into support and, yes, it is a bug for NetAdvantage 2007.  Support will issue a bug fix.

Thank-you, Mike :)

Thank you very much for the reply. 

I tried using the code snippit you gave me to my sample project, but I did not have any success.  As requested, I put the snippit in after the IntializeComponent of the form.  I was still able to Ctrl+Tab to the next Tab.

I removed the if statements so that the code would remove all mappings and it still didn't work.

I created button Click event for one of the buttons  on the TabControl and got a Count on KeyActionMappings.  It was zero (this was for the code that removed all key mappings).  Yet I was still able to press Ctrl+Tab to move to the next tab.

Is there some other property I should set on the ultra tab to make this work?

The following code will remove the key action mappings for Ctrl+Tab and Ctrl+Shift+Tab from an UltraTabControl:

List<KeyActionMappingBase> mappingsToRemove = new List<KeyActionMappingBase>();
foreach ( KeyActionMappingBase mapping in this.ultraTabControl1.KeyActionMappings )
{
 if ( mapping.KeyCode == Keys.Tab )
 {
  if ( mapping.SpecialKeysRequired == SpecialKeys.Ctrl ||
   mapping.SpecialKeysRequired == SpecialKeys.ShiftCtrl )
  {
   mappingsToRemove.Add( mapping );
  }
 }
}

foreach ( KeyActionMappingBase mapping in mappingsToRemove )
 this.ultraTabControl1.KeyActionMappings.Remove( mapping );

You can use this in the constructor of your Form after the InitializeComponent call.

Is there a way to disable the default Ctrl+Tab behavior while in Wizard mode?

If I created a blank project, add an UltraTabcontrol with three tabs and a command button on each.  I can hit ctrl + tab when the button has focus and the control will move to the next tab.
