Playlist not working properly in Sonar 8.5 Studio

so far it is working ok, but the playlist I use is only 8 songs long. I've been using playlists as long as 40 songs with Cakewalk 9, then Sonar 2.2 sonar 5, 7, 8.3, and now in 8.5, and I am sure that they all ignore the 'allow only one project open at a time" setting in global (mayve cakewalk9 was different). My theory is that although the songs stay up the data is unloaded. The crash you get could could be something else (or not). I'm assuming you use playlist for live, so go to audio options and increase your latency, it will make no difference for live as you are playing along with what you hear rather than monitoring for an overdub. Of course if you use the same pc for studio, you'll want to reduce the latency for sessions. My live laptop is running 8.5 on an IBM core2 duo 2.5 ghz and even though I can the latency down to 2.9 for vey small projects I use 11 seconds (+/-) for live just to avoid any embarrasing crashes. Also for live you should consider not using any or many plugins, at least not in the separate tracks.
I wish playlist did more, back in Cake 9 it would resume from the position in the song where you stopped now it's always from the beginnig, wish you could have both PLUS (big wish) I wish you could assign hot keys or midi  for start and stop instead of just the spacebar
