Log in as demo.
Search for a contact (any contact will do).
Click on the contact to display it.
Tabview comes up with Summary, Contributions, Memberships, etc.
The Summary tab is selected and instead of a scroll bar on the right side of the view with the contact information visible, the scroll bar is on the left side of the view with nothing visible. Selecting a different view and then going back to summary fixes it.
Tested with Safari 2.0.4 on 10.4.9 intel and PPC.
