Yes, the first part of the config file reads as follows: "{"account_tracker_service_last_update":"13334489856807897","alternate_error_pages":{"backup":true},"announcement_notification_service_first_run_time":"13334506503682677","autocomplete":{"retention_policy_last_version":108},"browser":{"has_seen_welcome_page":false,"window_placement_popup":{"bottom":429,"fullscreen":false,"left":4,"maximized":false,"right":696,"top":28,"work_area_bottom":1170,"work_area_left":0,"work_area_right":1920,"work_area_top":0}},"
I've tried changing the window size fields to other values but this seems to make absolutely no difference at all. Alt+Enter has the same effect as I have previously described.
The game appears to be programmed using javascript.
