Research direction
The issue describes a UI bug where the editor pane becomes non interactive after opening an existing file, and the preview pane scrollbar has resize issues. To reproduce, open a .md file and observe the pane behavior. The code responsible for pane layout and event handling is likely in the editor view controller or window controller classes. Look for files like 'MPEditorViewController.m' or similar in the MacDown source. The scrollbar resize bug may be related to autolayout constraints or mouse event handling. The issue has comments that might contain additional reproduction steps or hints.
