Anyone know what this happens....?

1. Rotating vertical images to the WP library they end up being displayed vertically.

2. When I try to rotate them I cannot. The rotate arrows are grayed out.

What am I missing? Permissions? This feature does not work? What's the deal?

All I found searching the WP forums was a 2 year old answer from the same topic that said this feature is not yet supported.

Thanks.
