This happens a lot with Mail.app. What I do now is just use Cmd+0 to show the main Mail window, or Cmd+1 for other apps - Evernote and Skype come to mind. Another thing that annoys me to no end: alt-tabbing to Finder takes you to an open window in another desktop! I want to open a new window on this desktop. I guess the linked trick may help with this behaviour. Edit: Found a solution. Alt+Cmd+Space brings up a Finder search window on your current desktop. Good enough.
