 <p>I had the same issue on my computer. I believe it's caused by the icon cache in Windows. </p> <p>What I usely do is removing the icon, cleaning up the PC (with <em>CCleaner</em>), then, add the icon. </p> <p>Or you can just delete <code>/Documents and Settings/&lt;username&gt;/Local Settings/Application Data/IconCache.db</code> (<em>Windows XP</em>) or <code>/Users/&lt;username&gt;/AppData/Local/IconCache.db</code> (<em>Windows 7</em>).</p>
