Well, I won't prolong this discussion because we are both anxious for you to get back to programming clams
My only concern is that, while I see no need to change screensavers, someone later down the line surely will. And if, when they do, the SS disappears it will be unlikely that they will see a way to 'reinstall' it. It will just remain inactive, and of course fail to be a source of amazement and thereby a sales stimulus.
If MA3 fails to install in the right folder, so that it remains in the SS list, then maybe a caveat should be inserted in the readme, or settings panel, or someplace where a new user would see it.
ps. I added a sig so we will all know what systems we're talking about. Cheers...
