If I am editing a source file foo.py and am at line n, and then change focus to another source file and then return to source file foo.py the pycharm editor returns to the first line of the file. So I am continually trying to find the point where I was in each file I am editing. I've looked all through the preferences but cannot find anything that toggles this behavior. I have to just be missing it, since this is pretty basic functionality. Any idea where I can fix this behavior?
