I'm assuming you're using the Windows Pro style with the Enhanced taskbar.
Try turning off the Enhanced taskbar and see if that corrects the position of t he Start11 menu.
Try setting it to the left in settings and then back to center.
Try restarting Explorer.exe
As a last resort: If you installed 2.06 over the previous version, try uninstalling; restart; reinstall; restart, and see if that fixes it.
