I've noticed that the newest version of GUIDE8 no longer allows me to run multiple sessions simultaneously the way I used to. To verify this, I checked an older version (29 Aug 2008) I still have on my system. I can run as many sessions of that simultaneously as I want. If I start the 15 Sep 2010 version and attempt to start another session of it, I get the message: "Another version of GUIDE is already running!" Bill, did you mean for this to happen?
