Hi, I'm on Linux and using a CVS build of Csound. Recently I've been having problems with the FLTK windows not closing after stopping Csound. I'm using Blue to run an orchestra in realtime. After pressing stop audio stops and the FLTK widgets stay frozen, I have to do a killall csound in order to get the windows to close. I tried building without separate FLTK threads and the problem persists. Thanks, Hector
