I had the same problem with the Choosy Fluid app. Also, like Anna says, the Choosy app seemingly completely ignores rules involving new Fluid apps and will often open links pertaining to them in the default browser. One of my Fluid apps for Youtube actually isn't working at all now. When I launch it, it opens about 12 tabs and says loading, then opens Chrome and loads Youtube there. This needs fixing! Interaction with fluid apps is the only reason I installed Choosy in the first place...
