I recently rebuilt my computer, and after reinstalling emacs and orgmode the agenda window has a new, undesirable, behavior. After making any change, the window moves to place the previously edited location at the top of the window. For instance, if I complete a task on line 5, the window adjusts so that line 5 is now the first line at the top of the window. I've tried to illustrate below:

__________

L1: TODO task 1

L2: TODO task 2

L3:
TODO task 3

L4: TODO task 4

L5: TODO task 5

L6: TODO task 6

______________

after completing task 5 the window looks like this:

__________

L5: DONE task 5

L6: TODO task 6

______________

Any ideas? Thanks.
