Is there anyone using Safari 7.0 that is having problems watching college lectures on tergrity? Tegrity will start in my browser, but it will not playback any of the video streams of my classes. The lectures work in Chrome, although i am not the biggest chrome fan and would really like a work around for safari 7.0. Solved: I have found a solution for anyone interested. Safari -> preferences -> security tab -> manage websites settings -> click on silverlight and make sure you set the correct site for your tegrity lectures to 'allow always with no security restrictions' Restart or refresh your browser and you should be all set.
