Attachment: Wrong position of Panorama button in new window

If after Step 7, you open a new window, you will get a normal new window. However, when you maximize the new window, you will realize that the panorama button is wrongly positioned.

Note: in step 5 your 'current theme' must be a Aero theme.

This bug cannot be produced if you change your theme to Aero basic and back to Aero theme again. (because I tried it out, but no bug is produced.)

This should block beta 9/beta 10 release.
