I received an SOS from a fellow Captivate developer who was having a hate-hate relationship with the mouse click sounds he was hearing in his Adobe Captivate demonstration. He told me he had spent over an hour trying to figure out how to disable the mouse-click sound, project-wide. Project-wide? Heck, he was so frustrated at this point that he was willing to disable the mouse click sound, one mouse pointer at a time. The solution is actually quite simple, and can be used project-wide. I shared it with him and now I'm going to share it with you.
First, select any of the mouse pointers on any slide in your project. Then, on the Properties panel, open the Options group (if necessary) and deselect Mouse Click Sound.
