Not GP, but that's better than my Mac as a whole. Weird OS issues with the trackpad, login, or fan/cpu/ram usage despite nothing big running necessitate a restart at least once a week.
I would generally agree, except in this case that makes it one of the more stable pieces of software I am running on my mac. When it happens I have a single hotkey mapped to restart the service which recollects all my windows and usually fixes anything that was going wrong in ~3-4 seconds.
