Does the auto-export work with crashes? I also noticed today that, out of curiosity, I went and shut down stimuwrite and opened one of the exported files but it was blank. Not sure if it's a bug or not, but I thought I'd let you know.
Oh, I should note; I've noticed it doesn't seem to export right for me. I've clicked export, I've shut the program like usual, gone and opened the file and it's a blank slate. The beta tester in me has been bugging me to let you know XD
