Does anyone have this working correctly with the build 428? I'm trying to create a popup effect after 5 seconds that last for 2 seconds on a 15 second tile but it will not let me move the effect. I can make an effect longer from the right but can not shorten it from the left. I see a + sign that seems to indicate it can be dragged but it won't move. I've tried adding keyframes but they don't seem to do anything and I can see no way to delete them. The whole thing looks powerful but just doesn't seem to work as it looks like it should. Any moment now I'm expecting it to crash as it has done once all ready, and then it won't work at all without a complete reinstall again.
