Please remove the code that allows the preview window to "always be on top" of everything. Often I will be running Hoster and OtsDJ at the same time as I do a wedding with karaoke. This is such an annoying feature that you added. Make a check box in the options or setup dialog to allow for an "always on top" selection if someone would want it. Many of us do other things while running a KJ show.
What made you think "we" would love this feature? When I run the 5.01 and open a singers and search dialog I have to move them somewhere else because the preview window (yes, undocked to allow me to look at the computer and see the words) is covering them and I cannot get it to go away without making it a "docked" option.
