Description of Problem:
Removing all the tab pages from a tab control does not refresh the control
appearance.  Removing a tab page from a control that does not currently have
any tab pages causes an System.ArgumentOutOfRangeException (-2)

Steps to reproduce the problem:
1. Start with a form and tab control with 2 tab Pages, and a button
2. Add on-button-click code to remove the 2 tab pages using
tabControlN.Remove(tagPageN)
3. 1st button click: tabs are removed, but tab Control is not refreshed.
4. 2nd button click: System.ArgumentOutOfRangeException occurs


Actual Results:
3. 1st button click: tab control is not refreshed, still displays 2 tab pages.
4. 2nd button click: System.ArgumentOutOfRangeException occurs

Expected Results:
3. 1st button click: tab control should be displayed empty, with no tab pages.
4. 2nd button click: tab control should be displayed empty, with no tab pages.


How often does this happen? 
Consistent.
