Full_Name: Joachim Harloff Version: 2.0.1 OS: MacOS X 10.3 Submission from: (NULL) (84.152.129.217) Hi, I had a RAM intensive calculation run (anova (lm ... ), whcih allocated about 400 MB of RAM. Then I tried to use a MAC OS Classic statistical program additionally. During startup of MacOS Classic the Unix system crashed. Some Unix lines appeared on the screen (sorry, I didn't understand a word) and everything was frozen. I had to restart the computer. I do not think it was because of memory lack, since I have 1.7 GB of RAM available and the programs running / tried to open would not even consume the half of that. Regards, Joachim
