icons disappeared

icons disappeared

All of my icons suddenly disappeared..... Again.

When I used jquery mobile 1.0.1, same thing happened.  To fix it, I just downloaded the new version, 1.1.1 and started over.  Whatever the problem was, it was fixed.

Now again, same thing.  But I'm not starting over.  Anyone have any ideas? 

I'm just developing and previewing on a pc with windows 7, but in an emulator the icons were missing as well.
