I've recently applied fixpack2 to my WebGUI, 7.3, after the fixpack I've rebooted my vm, started TIP, everything works except I don't see the logout button.
I've restarted the application, browser and still face the same problem. I then tried to clear java cache and that fixed the issue. I revisited the README file come with the fixpack and found this was mentioned in the file.
conclusion: Read every bit of the README file is absolutely important.
