Finder always jumps to top of window in list view
It's possible that there has been some corruption to that folder's .DS_Store file, which the Finder uses to remember it displayed that folder last time.

You'll probably want to check out Consequences of deleting .DS_Store before you actually delete it so you know what to expect.


Make sure the Finder doesn't have the relevant folder open.
Open Terminal.app in /Applications/Utilities. 
Type cd followed by a space.
Drag the icon for the folder with the issues into the Terminal to automatically fill in the full path to that folder, and press enter.
Enter rm .DS_Store.
You might need to Relaunch the Finder.
