Hi, I am running Mac OS 9.2. I have plenty of RAM installed - 897 mb. I notice that frequently I will have opened two or three programs, and still have plenty of RAM left, but my computer suddenly slows down...and I have to restart. I've gone through the ZAP pram thing, rebuilt desktop, and run Norton. I do NOT have virtual memory on. I thought this problem would go away when I recently added 512 mg of RAM. Any suggestions would be greatly appreciated. Thanks!
