I'm new to flowlab, and I'm having some trouble. I'm trying to add some behaviors to my game. About 80% of the time I try to move a behavior (click-and-drag) it disappears. Also, if I click on a behavior to look at details about it, when I click OK to close the detail window, the behavior disappears. This is a school project I need to complete soon, so any help would be appreciated. Thanks!
