Something about my general pet peeve, communication. Could we please get build numbers published with releases? That way we would be better off discussing specifics, or handle possible typos or broken installations.
As I mentioned earlier, my installation - invoked via Windows Update - tells me it is SP2 when I look in the Software.CPL but the About box gives me SP1
It also shows a build number, which could be used to ID where the mistake lies. I am now close to convinced it is SP2, simply for the different behaviour of certain tasks, like having a mini-preview with a circular arrow icon while xMedia builds views in the light table etc.
