I checked your very informative page and also the Activity Monitor. While Activity Monitor was open, I ran one of the formerly crashed spreadsheets through its paces. Page outs and Swap used remained at zero throughout the exercise. With all the calculations and circular references, I can see how the internal pointers would get a real workout. Thanks a lot for the insight. I really appreciate it.

I can buy an additional two Gb RAM from Apple for $499.00 or I can buy an iPhone with a whole lot of RAM and I can chuck my Palm Centro that is really weak at surfing the web. Hmmm. (ooops! Subject Change Alert!)
