When using Interface skin, such as "Office 2010 Black", some windows are missing text, or it's invisible due to the scheme. For example, in the Object Explorer, right-click an object and go to Version Control Wizard. When the first menu opens, there's no text.
The following other skins are also affected:
Change the skin to an unaffected theme in the Configuration Wizard.
Waiting for a fix in a future release.
