I currently have, on my iMac, a 47:8:40 uptime, in Days:Hours:Minutes. That is also my record. To find your uptime, open the Terminal (Applications->Utilities) and type "uptime" but without the quotes. This will be interesting to see, as my iMac has also been folding constantly for those 47 days. BTW, it is running Jaguar, so most of the recent security updates and such have been unneeded. Do tell your uptime!
