Since the Mac version went 64 bits, I've experienced quite a few complete freezes of Cool VL Viewer, forcing me to kill it. It seems to happen in places with quite a few people around. Camming around seems to be an aggravating factor, but I got some while I was just standing there. I couldn't really figure out a common factor. The freeze happens all of a sudden: one second, the viewer works fine, and the next one, I'm stuck with the dreaded spinning rainbow pizza, or sometimes without any mouse pointer at all. The icon in the dock says "Application not responding", and the only choice I have to get everything back to normal is to "Force stop" it.
Here is my system info:
I'm attaching the log file I got. Since I killed the application, I'm not sure it actually includes everything… If there's a way to make sure the log file is always complete even when the application gets killed, please let me know: I'm getting these quite often, I'm sure I can get another one quickly enough.
