After you selected minimized did you click the apply button?
I like listening to an online radio station (through Windows Media Player) every time I use my computer. So, I put a shortcut to the playlist file in my Startup folder. But, even though I selected "Run: Minimized" in its Properties dialog box, it always runs in a normal window. (Then I manually minimize it.)
So, how can I force the shortcut to open Windows Media Player in a minimized window?
I have Windows 7, with Service Pack 1, and Windows Media Player version 12.0.7601.17514.
