Hi David, I did some tests over running as a limited user with just the normal taskbar at the bottom of the screen (no auto-hide or anything), and unfortunately I was not able to reproduce the problem of the "full screen" arrow not showing up.

If you have any more information you can give me, such as do you have particular configuation of the desktop (like additional toolbars, etc...), or any additional system utilities running that may alter how the desktop behaves, please let me know, maybe that will help me to be able to reproduce the problem.
