Still happening. One peculiarity I just know noticed is that when i mouse over any of the large icons (pc, show the desktop, and device notifier) as well as the desktop switcher, the tool-tip highlights are at the top. However, when i mouse over icons in the quick launch applet the tool-tip highlights are at the bottom, except for the quick launch icons in the bottom [of three rows] row of the quick launch applet, they appear at the top. This is indeed a tough bug to squash. [at least for me].
