No. I never have "automatically resize" checked as default. Yes, I knew "Zoom to Fit" wasn't one of the option that Skim attempts to save when you set the default (since it has no tick on it), but for some reason (when I toggle in and out with the same PDF file at least) it does seem to remember this zoom factor sometimes (I can't find a pattern to describe what it takes, but after a few tries it sticks) and even a slightly manually altered one (e.g. zoomed out a bit)! I can't explain why, especially not the latter (maybe the others happen to be defaults). But this is a tangent, although perhaps an interesting one. To answer your question: my zoom level is such that the screen is larger than the width of the page (in a standard US letter PDF compiled from LaTeX). That is, I am either at "zoom to fit" (which fits the page margins exactly, given that I am in single page continuous) or slightly zoomed out from there (so I can see more of the page). By the way, usually I have the same zoom (relative to the frame) in the full screen and in the normal view. But I do get this page-scrolling-upwards behavior consistently at many zoom levels. I also played around and notice that I get it with many other settings: PDF crop vs. media (usually have it at crop), with or without page breaks (I usually have it without breaks), etc. It also happens with the double page continuous view. The only way I do not get it is when I am in the single or double page modes without continuous.
