i was using 3.0 with no problems....then went to resize the singer display....clicked on it and it disappeared....ended up scrambing and moving my preview display to work for the words....but it is nice to be able to see the selected song come up on my computer....did the regedit....completely removed and reinstalled hoster...but to no avail....when I go to run songs they only show up in my small preview....I used to click on the display and it would go full screen....doesn't do that anymore. PLEASE HELP!!!!
