Main Menu slide bogging down presentation
I have a 37 slide presentation or so. Around slide 17 I have a "main menu" where users can click on any of 7 buttons which branch them to a 3-4 slide scene, then returns them to the main menu. In preview this main menu slide works smooth.. Upon publishing however this slide is bogged down, doesn't animate on properly - then after about 20 seconds will function very slowly.
Anyone know what this is? - each of the 7 buttons has a few states, nothing crazy.
