Windows – Why does Adobe Acrobat scroll so slowly, and what can I do about it

I often am forced to view long PDF documents either in browser or out of browser. When I'm forced to use such documents, it's always frustrating, because whenever I scroll the document, the viewer "stutters" — and it's at least some 30 seconds later before Acrobat relinquishes control of my mouse pointer. (I've found that if I Alt-Tab out of Acrobat, everything finishes scrolling instantly, and I get my pointer back)

I suspect that the issue lies in not having the world's greatest graphics card in this laptop (an NVIDIA Quadro NVS 160), but it scrolls so slowly that I don't think this is just a hardware problem.

Has anybody had this problem before? What does one do about it?

EDIT:

Interestingly, this only seems to occur if I use the "middle button scroll" on the laptop keyboard; if I plug in an external USB mouse and scroll that way the problem seems to go away.

EDIT2:

Replacing Adobe Reader with something else is not an option. Using alternative readers has bit me in the a** enough times that I don't want to deal with it. Unless it supports reading anything in a PDF that Reader X does, I'm not interested (and no third party reader does so).

More to the point, this occurs in other applications on this machine than Adobe Reader — it's just that in Reader this problem is most noticeable. Using Foxit Reader, for instance, does not change the problem; it's still just as poor there as it is in the first party tool.
