It seems that when setting the window position to 0, 0, or 1920, 0, the 0 value is not saved.
This has been fixed and an update will be available sometime this week.
Thank you for reporting the bug! Someone else sent me an email this morning mentioning this so it was already on my radar, but it never hurts having confirmation from multiple sources.
The update has been published and should be available within the next hour.
