I am a new Captivate 5.5 user and I have been using the Adobe Connect Training material to come up to speed on the product. However, I have noticed that when viewing presentations in Connect, over time, the audio and video eventually are completely out of synch. What is being discussed (in the audio) has nothing to do with what is being shown on the screen. This happens on all Connect Training videos. I have a high-speed Internet connection and I never have problems with streaming content from other sources such as YouTube, etc. What am I doing wrong?
