In Windows Vista or in Windows Server 2008, when there are right-aligned tabs, the tabs are misaligned in an application that uses rich edit controls

SYMPTOMS
On a computer that is running Windows Vista or Windows Server 2008, you edit content in an application that uses rich edit controls. However, the tabs in the application are misaligned.

For example, if you change a left-aligned tab to a right-aligned tab, all the tabs after the left-aligned tab are changed to right-aligned tabs.

Note This issue does not affect the tabs that appear before the left-aligned tab.
