Can anyone else confirm this problem?

This is on Solidworks 2013 x64 and Windows 7 x64

1. Open Windows Explorer to a folder with a Solidworks file.
2. Open Solidworks 2013 and maximize Solidworks.
3. Bring Windows Explorer to the front by clicking on the tab in the taskbar.
4. Double click on your Solidworks file.

Does Solidworks "unmaximize"? It basically does the same thing as hitting the restore button.

I have tested this on a fresh install of Windows and Solidworks.

The problem didn't exist in Solidworks 2012, but does in Solidworks 2013.
