Joemikeb:
You were the first responder to my distress call in the long thread, "When is an Excel file getting too big?" You also recommended OWC as a reliable vendor of RAM. It was your advice, coupled with reports that Excel 2008 was more comfortable with Snow Leopard than 2004, that led to my making those two changes.
Upon installing the extra RAM and upgrading to MS Office 2008, my troubles ceased. My machine continues to run flawlessly. It is the finest experience I have ever had with a computer. It is a tribute to the quality of Snow Leopard and the good advice given on this forum. Thank you for your help.
