Some users report that the switcher dialog does not stay on top while it is displayed, but one can navigate through this dialog using mouse even if it is completely overlapped by some window. This bug is reported to be user profile specific. Some user profiles on the same machine may encounter this bug, some not. As discovered, the problem is sometimes caused by desktop gadgets system. After killing sidebar.exe process (which hosts the gadgets), the problem disappears. After restarting sidebar the problem appears again. This bug also happens when ipoint.exe, the Microsoft Intellipoint mouse driver, is running. Other programs causing this behaviour were reported as well.
