Cursor jumps to top of source file

[dirvine]

This seems to be a continuous issue. I love the script, but on linux I cannot get it to work. As I scroll down using any method, the cursor jumps back to the top of the file, normally not getting past the license part (40 or so lines).

Here is my vimrc if it helps. I have tried commenting out almost everything
