Whenever I try to Flag an email with the red Flag, Windows Live Mail will rearrange multiple emails and Flag them all at the same time.  There does not seem to be a pattern for this.  If I unflag the same email, all of the emails go back in place in their original spots.  Therefore, I am unable to use the Flag feature.  I do not have this problem with another PC using Live Mail.  I have not changed any configurations.  I tried to run the repair Windows Live in the Control Panel -> Uninstall/Change.  This did not help.
