With YAF 1.9.5 RC1, and using the Orange-Gray theme, when new users try to register with Internet Explorer 9, the terms sheet "accept" and "decline" buttons do not show up. Other themes work OK, and other browsers (eg. Firefox) are also OK.

The buttons are actually there, but the text and background colors make them invisible. You can hover and see the link actions appear on the screen.

On the next screen, when entering other profile information, the entry boxes have no visible borders, so entry is difficult.

Have not tried *all* themes, but others do work OK, so the issue might be limited to Orange-Gray.
