Just downloaded and installed beta 126.96.36.1995, and when launching the batch manager it closes by itself after a second or two. No video loaded in the editor or anything. No existing batch job in the queue from some previous session. Just a fresh start of the program and the batch manager. I have never experienced this with any earlier version to my recollection. Windows 10 64bit, Intel Core i7 with integrated graphics (Intel HD Graphics 4000), no GPU card.
