I love having my Taskbar on the right side of my screen because it maximizes the vertical workspace I have on my widescreen monitor. This is important when working on a laptop- especially because the taskbar was made larger in Windows 7. The main problem I have found while working with this config is this: I cannot lock or reboot my computer in the normal way (via the start menu). Here is a screenshot of what I'm talking about:

Doesn't look like a problem at first, but when you move your cursor off of the arrow beside the "Shut down" button, what happens? The menu containing all of the other actions closes making it impossible to select any of the options contained in the menu. How a bug like this gets through the beta phase is beyond me. Anyone know of a fix?
