Thanks for the reply.
I think we may be talking at cross-purposes. I'm talking about the little rotating wheel thing that appears on the mouse pointer when something is loading (the times when Windows has a little hourglass on its pointer). (Since seeing a review of "Afterliff" I can't help thinking of that little spinny thing as a "sorrento"
) I'm still running it off the Live DVD, so I don't think anyone can have added any effects that aren't in the standard package. These little wheels aren't unique to Linux, I see them all over the place, but I'm used to how to turn off or avoid most of them. Likewise, one appears in place of the Z on the Zorin Menu if you take Zorin by surprise, and the installed version of Firefox is riddled with them but I can get on to replacing that with my usual version (or the Linux version thereof) if I can fix Zorin itself - if not, there's no point anyway, because I won't be able to use it.
I'm not bothered about the Z splash screen.
I don't mean I'm talking about things that are unique to Linux; when I first got Windows Vista I spent a long and painful few hours hunting all these little animations down and turning them off, and I'm in a worse phase now than I was then; I just couldn't do it now. I'd forgotten quite how hellish it was for me until I tried out Zorin OS.
