You are correct...my bad.
OK if you don't select a skin than the tabstrip automatically chooses the default skin in the RadControls folder so you can modify it to give you the desired effect.
|RadTabStrip_Office2007 li a.selected .innerWrap |
| background: url('images/tabMiddleOn.gif') right top no-repeat; |
| cursor:pointer; |
| /* IE 5 Win */ |
| _cursor:hand; |
Where Office2007 is the name of your Skin which in the case of using the Default skin would be Default.
I found this here (google"clickselectedtab cursor site:telerik.com" for more options):http://www.telerik.com/community/forums/thread/b311D-kcgae.aspx
It is a little out dated so the format for your class/skin/element might be a little different, but hopefully this is a good starting point.
