Muse audio player widget does not work correctly in Safari but works fine in Chrome and Firefox.

The audio player will display and play in Safari but the progress bar will not fuction the first time played. The second time played the progess bar works as it should in all respects. If I refresh the page the player must play once before the progress bar will fuction again. The player works perfect in Chrome and Firefox. When the player is playing the first time you will get a "aN:aN" if you place your curser on the progress bar. Hs anyone else experiened this behavior?
