I have a Droid X and have been able to download a few songs but have been able to use only some as ringtones. So I've done something right a few times but can't ID what that is so I can be consistent. Here's what happens:

The song downloads and when it's finished, I should be able to hit the menu key and select the "use as ringtone" option. The problem is that sometimes, after the song downloads, the window closes immediately and I never get the opportunity to press the menu key. This happens time and time again to the point where I finally give up. What makes this work some of the time and not work some of the time?

Any help with this would be greatly appreciated. Thanks.
