Hmmm, depends on what version of GSOS you were using I'd guess. Things really smoothed out under GSOS v5.04, and I can't recall the last time I had a system crash under v6.01. I've had more mysterious crashes on my PowerBook running System 7.1 than I've ever had on my GS in recent years.Even then, I'd consider the OS on my Mac pretty satble as it doesn't happen too often. -John
