I just noticed an issue with the Global Address Book display.
If I click the Address Book icon in the Taskbar, I am taken to the page where the address book displays correctly.

However, the Address Book sidebar on the Compose Window is messed up. I have to click on the area with the orange arrow to make the Global AB drop-down. I do not have access to my Personal Address Book on this screen either.

This is the latest version of the GAB plugin and RC 0.9.5.
Thanks
This appeared to happen due to a failed upgrade from 0.8.7 to 0.9.5. After a fresh install, it is displaying correctly again.
