If I set my nudge distance to say, 2in, and then use the arrow keys to move a selected object around the screen, when I nudge back to where it started from, it no longer is in the original position. In other words, the nudge did not stay at 2in during each arrow click. It usually happens in only one of the two directions, up/down or left/right nudge. It MAY be triggered when the object crosses over the dimensions of the page setup even if you are outside the page itself the whole time. In other words, imagine vertical and horizontal guidelines passing through the edges of the page. Regardless of where the object is on the work area, if it is nudged ACROSS one of those boundaries, that MAY be what triggers this, but don't know for sure.
I use CS3 13.0.2
Thanks.
One condition that causes your problem is having View> Snap to Grid (Ctrl + Shift + " is the toggle) on.

I believe I checked for that on a number of occasions and it did not seem to be that. When it comes up again, I'll make doubly sure. What bothers me about THAT eventuality is that since nudge is set to a SPECIFIC value, and the arrow keys respond to that specific value, Illustrator should be smart enough to realize that Snap-to-grid should be ignored whenever the arrow keys are being used to nudge. Otherwise the logic of it all is inconsistent.

Post any interesting findings for others.
