Hoster 5.09 Has been released May 28, 2013

1) First time using 5.09. Sporadically, during a song, I hear a buzz that lasts for about 1 second. After that, the music and lyrics go out of sync. I set the sync to -.75 and all is well. If the buzz occurs during the same song, I have to set the sync to -1.5 and it's fine.
2) When doing a search while a song is playing, both displays (mine & the singers') flash. This again is sporadic. I've done all the updates. These conditions are very annoying to my customers and myself. Any ideas?
