Mike,
I'm seeing random instances of SCS freezing for varying intervals of up to 30 seconds with no specific pattern. Sometimes it's when using the editor - screen sometimes goes white, seomtimes unchanged, but both with revolving blue circle for the duration. At other time I can trigger a cue and get a long delay before the cue fires up to 30 seconds later. I can't reproduce any specific instance, it seems random.
I have 3 log files, all of which should show different instances of the problem, which I have sent to you.
Thanks,
Dave
