User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a1pre) Gecko/20091117 Minefield/3.7a1pre Firefox/3.5

When starting Minefield from a shortcut pinned to the superbar, a second icon is spawned.

Reproducible: Always

Steps to Reproduce:
1. Locate the Minefield shortcut from 'All Programs' menu.
2. Right-click and select 'Pin to Taskbar'.
3. Launch Minefield from newly-created shortcut on superbar.
Actual Results:  
A second icon is spawned on the superbar to represent the running instance of Minefield.

Expected Results:  
The Minefield taskbar icon turns active to represent that running instance of Minefield.

Problem occurs on Win7 Ultimate 64-bit. A workaround to prevent this behavior exists:

1. Launch Minefield from the 'All Programs' menu.
2. Right-click the Minefield icon in the superbar and select 'Pin this program to taskbar'.

When created in such a manner, the superbar shortcut will not spawn a second icon when launched.
