Can you post log files for this case? The inlcuded fix was for a slightly other problem, that the renderer sync was not transfered back from (ending) player to MainForm
Sure,
but im not 100% sure what exactly the issue is. @kilik360 reports here that if a video ends, the refresh rate does not get set right.
And then later reports of blackscreen and having to kill MP2.
What of these two you suspect is caused by AtmoLight? My guess is only the second one?
