I have Milkdrop2 on a second Monitor (HD TV) via HDMI cable. Almost every time the song ends and switches to a new song it will crash. If Milkdrop2 is turned off it will not crash. This is for version WACUP_Preview_v1_99_27_21136_x86. I'm sorry if this has already been reported. I did not see it in the comments. It dose not do it in the previous builds.
